Quick answer: A Mercury repower needs more than just the motor. Controls, steering, gauges, wiring, and the right prop together add CAD $2,000-$6,000 to the install. Mid-range motors (40-115 HP) typically use a binnacle or side-mount control, hydraulic steering at 115+, and SmartCraft-Connect or analog gauges. V6 motors (150-225 HP) typically use binnacle controls, power-assist hydraulic steering, VesselView display, and dual-battery wiring. The matrix below shows what fits what.
If you've gotten a Mercury repower quote that just lists "rigging: $2,500" with no breakdown, this guide is for you. Rigging is the part of the quote dealers love to leave vague. We don't operate that way. The components you choose for controls, steering, gauges, wiring, and prop are real engineering decisions, with real cost tradeoffs, and they affect how the boat actually feels at the helm.
This is the canonical reference for Mercury repower rigging in Ontario. It covers the three core decisions (controls, steering, gauges), plus the wiring and prop work that come with them, for Mercury motors from 40 HP up through the 225 HP V6. We pulled the configurations from the actual repowers we do at Harris Boat Works on Rice Lake in the Kawarthas (Ontario), with real CAD prices and the reasoning behind each pairing.
If you're shopping a portable (under 25 HP) or a Verado V8/V10/V12, the rules are different. We focus here on the 40-225 HP repower zone where the bulk of Ontario decisions get made.
Why Rigging Is the Quote Line Most Buyers Underestimate
When a buyer thinks "Mercury repower," they think about the motor itself. Reasonable. The motor is the most expensive single component and the one with the spec sheet you've been studying.
But the motor doesn't move the boat by itself. Between the motor and your hand on the throttle is a chain of components: control box, throttle and shift cables (or the digital wiring that replaces them), steering ram, helm pump, hydraulic lines, gauges, key switch, kill switch, battery wiring, and the prop. Get any of those wrong and the motor underperforms or the install costs jump.
Three patterns we see at Harris Boat Works:
- Buyer reuses old controls that don't match the new motor. A 1998 binnacle from a carbureted 90 HP doesn't always work cleanly on a 2026 Mercury 90 EFI, especially if the wiring is corroded or the kill switch has worn out. The "savings" turn into a service call mid-season.
- Buyer skips the gauge upgrade. A new SmartCraft-equipped motor connected to old analog gauges loses about 80% of what the motor knows about itself. No fault codes, no fuel economy data, no engine hours, no warning before something fails.
- Buyer cheaps out on hydraulic steering. Cable steering on a 150 HP boat works, but it's heavy, imprecise, and tiring on a long run. Hydraulic adds $1,500-$2,500 and changes how the boat feels.
The matrix below is what we'd actually quote for each HP class. It's not exhaustive (there are always edge cases), but it's the typical setup that works for Ontario boaters.

These are typical configurations. Your specific boat, helm, console, and budget will move the numbers. But this is the shape of the conversation when we quote a repower at HBW.
Controls: Binnacle vs. Side Mount vs. DTS
The control box is what you put your hand on at the helm. There are three main options.
Binnacle (Top-Mount) Controls
What it is: A single lever that mounts on top of the helm console. Push forward for forward gear, pull back for reverse. Usually includes a neutral lock, throttle-only mode (for warm-up), trim/tilt switches, and a kill switch lanyard. The standard for runabouts, bowriders, fishing boats, and most pontoons with a console.
Mercury options:
- Gen II Single Lever (mechanical): The workhorse. Connects to the motor via push-pull cables. Used on 30-300 HP motors. CAD $700-$1,200.
- Gen II Single Lever DTS (Digital Throttle & Shift): Same physical lever, but the cables are replaced by an electronic harness. Smoother shifting, supports multi-engine sync, integrates with SmartCraft. CAD $1,400-$2,400.
When to pick which:
- Mechanical is fine up through 200 HP if the boat is single-engine and you don't need digital integration.
- DTS becomes the right call at 250+ HP, on twin-engine setups (sync is a real benefit), or if you want VesselView integration to feel seamless. DTS also opens up cruise control and SmartTow features on supported motors.
Side-Mount Controls
What it is: A control box that mounts on the side of the helm console (or on a pedestal). Same single-lever function as a binnacle. Common on tiller-helm pontoons that have a remote console for a passenger or co-pilot, and on smaller fishing boats with limited dashboard space.
When you'd use it: Smaller boats (40-90 HP), some pontoons, anywhere a flush-mount binnacle won't fit on the dash. Less common in modern Ontario repowers, but still in the catalog.
CAD $400-$800. Mechanical only (no DTS in side-mount form).
DTS (Digital Throttle & Shift)
What it is: Mercury's electronic control system. Replaces the mechanical throttle and shift cables with a wiring harness that carries digital signals. The lever feels the same in your hand, but underneath, the motor responds via electronic actuators instead of cables.
Why it matters:
- Smoother shifting. No "clunk" between gears. The motor's ECU manages the transition.
- Multi-engine sync. On twin-engine setups, both motors shift and throttle in perfect lock-step automatically.
- Cruise control / SmartTow. Supported features that aren't possible on mechanical setups.
- Integration with VesselView. All the engine data flows through the same harness.
When DTS is mandatory: All Mercury V8 (250-400 HP) and V12 (600 HP) motors are DTS-only. They don't accept mechanical controls.
When DTS is optional: Some V6 models (150 Pro XS DTS, 200 Pro XS DTS, 225 ELPT Pro XS DTS, 300 Pro XS DTS) ship as DTS variants, with a non-DTS version typically available for $1,500-$2,500 less. Choose based on whether you value the digital benefits enough to justify the cost.
For most single-engine Ontario repowers under 250 HP, mechanical is the right call. DTS earns its keep in twin-engine, performance, or premium-helm applications.
Steering: Cable, Hydraulic, or Power-Assist Hydraulic
Steering is the most underrated rigging upgrade. Most repowering boaters notice the difference at the helm before they notice anything else about the new motor.
Cable Steering
What it is: A mechanical cable runs from the helm wheel to the motor's steering arm. You turn the wheel, the cable pulls, the motor pivots. Simple, cheap, durable.
When it works:
- Up through 90-115 HP on most boats.
- Pontoons (lower steering loads).
- Tiller boats (no helm steering at all).
When it gets tiring:
- 115+ HP on V-hull boats. The cable load gets heavy enough that long days on the water leave your arms aching.
- Any boat where the operator does fine maneuvering at speed (waterskiing, tournament fishing).
Cost: CAD $300-$700 for the cable + helm assembly.
Hydraulic Steering
What it is: A hand-operated hydraulic pump at the helm pushes fluid through hoses to a hydraulic ram at the motor. The ram pivots the motor. Smoother, lighter, and self-centering at speed.
When it's the right call:
- Most 115-225 HP boats. Standard recommendation for V6 motors.
- Any boat over 18 ft.
- Anyone who finds cable steering tiring.
Brands: SeaStar Solutions (formerly Teleflex) is the dominant brand. SeaStar Pro is the entry hydraulic kit, SeaStar HC5345 is the heavy-duty version for V6+.
Cost: CAD $1,500-$2,500 for a complete kit (helm pump, hoses, ram, fluid). Add another CAD $300-$500 for installation labor.
Power-Assist Hydraulic
What it is: Same hydraulic system, but with an electric pump that does most of the work. Your wheel input opens a valve; the pump muscles the motor. One-finger steering at any speed.
When you need it:
- Most V6 (150-225 HP) repowers, especially for twin-engine setups or boats over 22 ft.
- Boats with high-friction motors (older Verado I6 retrofits, for example).
- Anyone who really values low effort at the helm.
Cost: CAD $2,500-$4,000 for the kit, plus install. The premium over standard hydraulic is real but earned for V6+ applications.
For most Ontario buyers in the 115 HP zone, standard hydraulic is the call. For 150+ HP, lean toward power-assist unless budget is the limiter.
Gauges: Analog, SmartCraft Connect, or VesselView
Gauges are how you see what the motor is doing. The gap between basic and good is bigger here than most buyers realize.
Analog Gauges (Tach + Fuel + Maybe Trim)
What you get: Mechanical needles showing tach (RPM), fuel level, and trim position. Speedometer is sometimes mechanical (pitot tube on the lower unit) or sometimes a separate electronic GPS speed display.
When it works:
- 40-90 HP outboards on basic fishing boats and small bowriders.
- Anyone who doesn't want to learn another screen.
What you give up: Engine hours, fault codes, fuel economy data, water temperature, oil pressure warnings, battery voltage history. The motor has all that data internally; analog gauges just don't show it.
Cost: CAD $400-$800 for a full set.
SmartCraft Connect (Mercury VesselView Mobile)
What it is: A Bluetooth dongle that pulls SmartCraft data from the motor and feeds it to the Mercury VesselView Mobile app on your phone. Add a SmartCraft tach to the dash for at-a-glance RPM, and you've got a complete dashboard at zero screen-real-estate cost.
What you get:
- Engine hours, RPM, fuel flow, trim, water temp, voltage on your phone.
- Fault codes with plain-English descriptions.
- Trip and lifetime fuel use tracking.
- Fault history exportable to your tech.
When it works:
- 40-150 HP boats where the buyer wants modern data without a dedicated display.
- Cottage boats where the phone is always at the helm.
Cost: CAD $300-$500 for the dongle + analog SmartCraft tach. Phone is free (you already have one).
VesselView (4, 7, 9, 12, or 902)
What it is: Mercury's color touchscreen displays. Shows everything SmartCraft knows about the motor in real time, plus integrates with chartplotters, fuel tanks, autopilots, and (on bigger displays) maps and sonar.
Sizes:
- VesselView 4: 4.3" screen. Basic motor data display. CAD $700-$900.
- VesselView 7: 7" screen. Motor data + smaller navigation overlay. CAD $1,200-$1,500.
- VesselView 9: 9" screen. The sweet spot for most V6 repowers. CAD $1,800-$2,400.
- VesselView 12: 12" screen. Big-boat applications. CAD $2,500-$3,200.
- VesselView 902: Mercury's premium 9" display, integrates with Simrad-style chartplotters. CAD $3,000-$3,800.
When you need one:
- Any V6 repower where the buyer wants real-time engine awareness.
- Mandatory in practical terms for V8/V10/V12 installs (these motors generate so much data that analog or app-only feels limiting).
- Twin-engine setups (single screen showing both motors is invaluable).

Wiring Harness and Battery Setup
The unsexy rigging that makes everything else work.
Single Battery + Basic Harness (40-90 HP)
For most basic outboard installs at this HP level, a single Group 24 or Group 27 starting battery with a basic Mercury wiring harness covers everything. Add a battery switch and a simple fuse panel for accessories (lights, bilge pump, fishfinder).
Cost: CAD $400-$700 for battery + cables + switch + basic accessory panel.
Dual Battery + ACR (115-150 HP)
Once you start adding electronics (chartplotter, fishfinder, stereo, charging port), the load on a single battery starts to add up. A dual-battery setup with an Automatic Charging Relay (ACR) keeps your starting battery isolated when the engine is off, so you can run electronics at the dock without worrying about a no-start in the morning.
Configuration:
- Battery 1: starting battery (cranking duty)
- Battery 2: house battery (electronics, accessories)
- ACR: combines the batteries when the engine is running (so both charge), isolates them when it's off.
Cost: CAD $700-$1,200 for two batteries + ACR + cables + switch.
Dual or Triple Battery + Switch Panel (175-225 HP V6)
V6 motors with VesselView, multiple electronics, livewells, and aerators benefit from a more deliberate electrical setup. Triple battery on tournament boats. Big switch panel with breakers for everything. Dedicated charging system so each battery sees the right voltage.
Cost: CAD $1,200-$2,000 for the full setup. Higher on tournament-prepped bass boats.
This is also where wiring quality really matters. Marine-grade tinned copper, proper terminal crimps, and heat-shrink-protected connections add up to a dry, reliable install. We've replaced enough corroded helm wiring on used boats to know that the difference between a $200 wiring shortcut and a $1,500 proper job is measured over years, not days.
Prop Selection by HP Class
Prop pitch is what translates motor RPM into boat speed. Wrong pitch means the motor lugs (pitch too high) or revs out without making power (pitch too low). Both wear the motor faster than they should.
The general guidance per HP class:
| HP |
Diameter |
Pitch Range |
Material |
| 40-50 |
12-13" |
11-15" |
Aluminum standard, stainless optional |
| 60-90 |
13-14" |
13-19" |
Aluminum standard, stainless for performance |
| 115 |
14" |
15-21" |
Stainless recommended for any sport use |
| 150 |
14-15" |
17-23" |
Stainless standard |
| 175-225 |
14-16" |
19-25" |
Stainless mandatory (aluminum can't handle the load) |
These ranges are starting points. Your hull weight, intended use (skiing vs. fishing vs. cruising), and the prop's blade design all push the right pitch up or down. Aluminum props are cheaper (CAD $200-$500) but flex at higher loads. Stainless (CAD $500-$1,200) holds shape, lasts longer, and recovers better after a strike.
For a deep dive on prop selection, including how to read your wide-open-throttle (WOT) RPM and dial in the pitch, see the Mercury propeller selection guide.

These are real-world numbers from quotes we build at Harris Boat Works. Your specific boat will move the numbers, but the shape of the breakdown is consistent.
For comparison context, the Mercury repower cost guide for Ontario walks through how these numbers fit into the full repower decision.
What HBW Includes vs. Charges Separately
Every dealer scopes a quote differently. Here's how we structure ours.
Always included in the rigging line:
- All Mercury-supplied wiring harnesses, control cables, and DTS harnesses
- Sea trial after install
- Break-in instructions and 20-hour service reminder
- Factory warranty registration with Mercury Canada
Quoted as separate line items:
- The control box itself (binnacle, side mount, or DTS lever)
- Steering system (cable kit, hydraulic kit, or power-assist kit)
- Gauges or VesselView display
- Battery, battery box, charger, switch, fuse panel
- Prop (we recommend a specific pitch and material based on your hull)
- Old motor removal and disposal (typically $200-$400)
- Custom helm console fabrication (rare; only if your old console can't accept the new gauges)
Not part of a standard quote:
- Trolling motors, fishfinders, stereos (we install if you want, but they're separate from the propulsion rigging)
- Trailer work (different shop, different conversation)
- Cosmetic restoration (paint, upholstery)
The full quote you get at mercuryrepower.ca/quote/motor-selection has all these line items broken out. No surprises at delivery.
Common Mistakes Buyers Make on Rigging
The five we see most often:
1. Reusing old controls "to save money." Sometimes works. Often doesn't, especially if the old binnacle is corroded inside or the cables have stiffened. A used control box that's three years past its prime can fail mid-season and cost more in tow fees than a new control would have cost up front.
2. Skipping the gauge upgrade on a SmartCraft motor. A 2026 Mercury 150 connected to 1998 analog gauges is using maybe 15% of the data the motor produces. No fault codes, no fuel economy display, no warning before something goes wrong. The gauge upgrade pays itself back the first time SmartCraft catches a developing problem.
3. Underspeccing steering on a V6. Cable steering on a 150 HP V6 boat technically works. After three hours on the water you'll hate it. Hydraulic is the right answer for any motor 115 HP and up.
4. Picking a prop pitch by guessing. Wrong pitch is the most common reason a "perfectly good motor" feels slow. The motor needs to hit its rated WOT RPM under your typical load. If it doesn't, the prop is wrong. Our prop selection guide walks through how to dial it in.
5. Single battery on a boat with electronics. A single battery running a chartplotter, fishfinder, stereo, and a starter is asking for a no-start morning. Dual battery + ACR is the right setup once you add electronics. The cost is small. The headache it prevents is real.
Frequently Asked Questions
How much does Mercury rigging cost in Ontario?
For a typical mid-range repower (60-115 HP), expect CAD $2,000-$4,000 in rigging on top of the motor price. For a V6 repower (150-225 HP), expect CAD $3,500-$7,500. The range covers controls, steering, gauges, wiring, and prop. See the matrix above for per-HP-class detail. Real all-in costs are at mercury-outboard-rigging-costs-ontario.
Do I need DTS on a single-engine V6?
No. Mechanical controls work fine on a single-engine 150-225 HP motor and save you CAD $1,500-$2,500. DTS becomes the right call on twin-engine setups, V8+ motors (where it's mandatory), or if you specifically want VesselView integration to feel seamless.
Is hydraulic steering worth it for 90 HP?
For most boats, no. Cable steering at 90 HP on a typical fishing boat or pontoon is fine. The exception is a fast bowrider or anyone who finds cable steering tiring. For 115 HP and up, hydraulic is almost always worth the upgrade.
What's the difference between SmartCraft and VesselView?
SmartCraft is Mercury's underlying data protocol (it's how the motor talks to gauges and accessories). VesselView is the family of color displays that show SmartCraft data. SmartCraft Connect is the budget option (data goes to your phone via Bluetooth). VesselView is the dedicated screen option. Full breakdown: VesselView and SmartCraft plain-English guide.
Can I run my new Mercury on my old prop?
Sometimes. If the old prop is the right pitch and diameter for the new motor's power and your hull, yes. More often, the new motor is a different HP or generation and wants a different prop. Run the WOT test after install: if the motor doesn't hit its rated RPM under typical load, you need a different prop.
How long does a full rigging install take?
For a mid-range single-engine repower (60-115 HP), typically 1-2 days of shop time once the motor is in. For a V6 repower with full electronics, 2-4 days. The lead time from "you sign" to "you take delivery" depends on parts availability for the controls, steering, and gauges, plus our shop schedule.
Will my old hydraulic steering work with the new motor?
Usually yes, if the ram is compatible with Mercury's tilt tube and the hoses are sound. We inspect the existing hydraulic system during the repower quote and tell you whether it's reusable, needs new fluid and seals, or needs replacement. SeaStar Pro and HC5345 systems from the last 15-20 years generally adapt.
What's the right shaft length for my repower?
Match the shaft length to your transom height. 20" transom = long shaft (L). 25" transom = extra long (XL). 30" transom (rare on outboards, common on bracket installs) = extra extra long (XXL). Measure your old motor or your transom directly. Full guide: outboard shaft length.
Do you offer financing on rigging, or just the motor?
Both. Mercury's financing programs apply to the full repower package, motor plus rigging plus install. We work through Mercury Canada's finance partner, with rates that change with their promo windows. Ask during the quote process and we'll match you to the right program.
Does HBW handle the trade-in on my old motor?
Yes. If your old Mercury is in workable condition we'll value it at trade-in time. Non-Mercury motors get evaluated case-by-case (we sell some on consignment, others go to recycling). The trade-in credit is a separate line on your quote.
