Quick answer
A Mercury repower in Ontario typically runs $11,000-$40,000 CAD installed, depending on horsepower, rigging needs, and controls, before HST. The motor itself is roughly two-thirds of the total. We post real installed prices. Build yours at mercuryrepower.ca, takes about three minutes.
Most repower cost guides give you a motor price and call it done. That's only about two-thirds of the answer. The bill you'll actually pay includes the motor, rigging, prop, installation, and sea trial. What you're trying to budget is the all-in number, and that's what we'll give you here.
2026 planning ranges by HP class (CAD, before HST)
| Project Tier |
HP Range |
All-In Range |
Common Boats |
| Tiller, motor-only |
9.9-25 HP |
$3,000-$5,500 |
Tenders, kickers, small aluminum tillers |
| Small remote |
40-60 HP |
$11,000-$15,000 |
16-18 ft aluminum, small consoles ¹ |
| Mid |
75-115 HP |
$17,000-$22,000 |
16-19 ft aluminum, small pontoons, fishing boats |
| 150 HP |
150 HP |
$23,000-$30,000 |
18-22 ft pontoons, runabouts, mid-size fishing |
| High-HP |
200-300 HP |
$35,000-$40,000 |
Performance bass, large pontoons, centre consoles |
¹ Capacity-plate footnote: 14 ft aluminum tin boats typically cap at 25-30 HP. Don't read the "small remote" tier as a 14-foot rec, check the plate on the inside of your transom before you spec a 40 or 60. The plate is the ceiling, not a suggestion.
Tiller motors (9.9-25 HP) are typically motor-only purchases, no rigging package. Above 25 HP, you're talking a full project: controls, cables, gauges, prop, and installation labour. Add 13% HST to any of these numbers.
What changes the final number
Six things move a repower quote up or down:
- Motor HP and family. The motor drives most of the price. A 9.9 ProKicker is a small line item. A 250 Pro XS V8 is the largest single purchase most boaters make.
- Whether you keep your existing controls. Mercury-to-Mercury repowers usually keep the existing control box and cables, which holds rigging to the low end ($500-$1,000 CAD). Going from a non-Mercury brand, or adding digital throttle and shift, pushes rigging to $2,000-$3,000 CAD.
- Steering. Cable steering on small motors is fine. Hydraulic steering on anything 150 HP and up is standard. Hydraulic conversion runs $1,650-$3,500 CAD.
- Prop selection. A wrong prop on a perfect motor costs you speed and fuel economy. We test on the water before you take the boat home. Aluminum props on motors up to 115 HP run around $450 CAD; stainless steel on 150 HP and up runs $800-$2,000 CAD.
- Gauges and wiring. Old analog gauges don't talk to modern Mercury motors. A SmartCraft display adds a line to the quote. Battery and harness refresh runs $275-$975 CAD.
- Boat condition. A clean transom and good wiring takes a day to install. A rotten transom or mouse-eaten wiring harness pushes labour from $1,400 to $2,500-$3,500.

Why we don't post specific motor prices in blog posts
Our actual prices are on the live configurator, always current, always in CAD, always for the specific configuration you're building, with Mercury MSRP and dealer pricing side by side on every model in the lineup. There's no point copying them into an article that goes stale the moment Mercury adjusts pricing. Our whole position is that you shouldn't have to call us or read a blog post to find out what something costs. The live configurator is built specifically for this job.
What we check before recommending a motor
Before we quote, we want to know:
- Boat make, model, year, and length
- Maximum HP rating on the capacity plate
- Hull condition (we tap-test transoms for soft spots)
- Existing controls and gauges
- What you actually do with the boat
- Where you launch
You can build a live CAD quote for your repower online at the Mercury Repower Centre. We won't quote a motor blind. If you build a quote through the configurator and the configuration seems wrong for your hull, we'll reach out before you proceed to install.
Order-to-install timing, be honest about the season
HBW is closed roughly December 1 through April 1. No service, no installs, no rigging work during those months. Here's how that actually plays out for repower timing:
- In-season (April-November): A clean Mercury-to-Mercury install runs 1-2 days of shop time. From order confirmation to pickup is typically 2-4 weeks, depending on motor availability.
- Off-season planning (November-March): This is the smartest time to lock in your spring slot. We take the consult, build the quote, and reserve the motor. Install starts the first week of April when the shop reopens. That's how you get first pick of motors and avoid the May rush, not by getting work done in February.
- Spring rush (April-May): Workable, but the shop is already filling with winterized boats coming out. Lead time stretches to 3-5 weeks. If your boat needs to splash by Victoria Day, get the quote done in February.
That's the honest version. Plenty of dealers will quote you "winter availability" and let you assume work is happening. We'd rather you know we're closed and plan around it.
When to repower vs. buy new
Repower makes sense when:
- The hull is solid (aluminum lasts decades, good-condition fiberglass can go just as long)
- The boat fits your family and use
- The motor is the only thing wrong with it
Buying new makes sense when:
- The hull has structural problems (soft transom, rotten floor, stress cracks)
- You've outgrown the boat
- You simply want a new boat (also a completely valid reason)
Most of the boats we see can be repowered for a fraction of what a comparable new boat costs. The math holds up most of the time. Some of the time, new is the right call. We'll tell you which one your boat is, even if it's the answer that costs us the sale.
What we see at HBW
Most repower quotes that come through our shop fall into one of three buckets.
The biggest is the 25-year-old aluminum Lund or Princecraft with a tired 60-90 HP. Owner wants a quote on a new 60-90 FourStroke, drops off the boat, and we work through controls, rigging harness, prop, and battery. Total installed typically lands in the $11,000-$18,000 range plus HST depending on HP chosen and what we find on the boat, see the planning ranges table above for the bands.
The second is a 21- to 24-foot pontoon getting a 150-200 HP repower. These run higher. Controls and rigging on pontoons tend to need more work, prop matching matters more, and a SmartCraft display often gets added or upgraded.
The third is the "I want a Pro XS" angler swap. Existing controls usually carry over but we always check rigging tube, throttle cable length, and steering hookup before quoting the install hours. Most regret stories start the same way: "I just wanted a bit more speed."
