Quick answer
Most Ontario center console buyers are running trailerable 18 to 25 ft hulls on Lake Ontario, the Bay of Quinte, or occasionally Georgian Bay. The right Mercury motor is usually a 200 to 250 HP V6 Pro XS for fishing-focused single-engine setups, or a 250 to 300 HP V8 for larger or premium twin configurations. The Florida offshore assumptions built into most center console guides do not apply here. Build a quote at mercuryrepower.ca.
Honest rigging pick
Single or twin Mercurys on a center console?
Most 22 to 25 ft center consoles run great on a single. Twins are about redundancy, not speed.
Choose single engine if
- ✓Center console is 22 to 25 ft
- ✓Most runs are coastal cruising, family use, dock-and-dine
- ✓Fuel economy and quiet operation matter
- ✓You want single-engine simplicity (one motor to maintain)
- ✓The boat is rated for a single-engine setup
Single Mercury 250 or 300 HP
Choose twin engines if
- ✓Center console is 25 ft or larger and runs offshore
- ✓Redundancy matters (limp-home capability if one fails)
- ✓You want maximum performance for chasing fish or rough water
- ✓Twin-engine handling at the dock is a feature, not a problem
- ✓The boat was designed for twins from the factory
Twin Mercury V8 outboards
When in doubt:Single 300 HP Verado handles most 22 to 25 ft center consoles beautifully. Twins are only worth it if you fish offshore or want the safety net of redundancy.
Why this guide is different
Most center console buying guides are written for a Florida audience: 26-foot offshore hulls, triple motors, blue-water fishing trips. That is not Ontario. The center console buyer who shows up at Harris Boat Works is typically running a trailerable 20 to 24 foot hull on Lake Ontario for salmon, the Bay of Quinte for walleye, or occasionally running Georgian Bay day trips. Different boats, different conditions, different priorities.
This guide is built around the Ontario reality.
The Ontario center console market: what actually moves
Ontario center console buyers are overwhelmingly trailerable. The boats that come through our shop look like this:
| Length |
Typical HP |
Common uses |
| 17 to 19 ft |
90 to 150 HP |
Bay of Quinte walleye, sheltered Lake Ontario, river running |
| 20 to 22 ft |
150 to 250 HP |
Lake Ontario salmon, Bay of Quinte, full-day trips |
| 23 to 25 ft |
200 to 350 HP (single or twin) |
Lake Ontario salmon runs, bigger-water Bay of Quinte |
| 25 to 28 ft |
250 to 400 HP (twin) |
Premium Lake Ontario / Great Lakes setup |
| 28+ ft |
Triple or quad |
Rare in Ontario, mostly U.S.-import boats |
The 20 to 24 foot trailerable class is where most of the real buying decisions happen. A 22-foot Boston Whaler Dauntless with a Mercury 250 Pro XS V8 is the most common center-console repower configuration we see.
Mercury motor families: which one for a center console?
FourStroke (90 to 150 HP)
Mercury's base FourStroke range fits the small end of center consoles: 17 to 20 feet, lighter hulls, moderate use. These motors are quieter and smoother than Pro XS at the cost of slightly less hole-shot and top speed.
Best for: 17 to 20 ft hulls, mixed fishing and recreation, customers who prioritize smoothness and fuel economy over peak performance.
Pro XS (150 to 400 HP)
The Pro XS line is Mercury's performance-optimized outboard. Available from 150 to 400 HP across V6, V8, and V10 platforms. Purpose-built for fishing use: optimized hole-shot, aggressive mid-range power, and competitive top-end speed.
For Ontario center consoles, Pro XS is the default recommendation for fishing-focused buyers.
- 200 Pro XS V6 (3.4L): Sweet spot for 20 to 22 ft hulls
- 250 Pro XS V8 (4.6L): Step up for larger 22 to 25 ft hulls or heavier loads
- 300 Pro XS V8 (4.6L): Performance upgrade for 23 to 25 ft hulls, tournament application
Best for: Fishing-focused center consoles, 20 to 25 ft hulls, buyers who want aggressive performance and do not need quiet cruise.
Verado (200 to 600 HP)
Mercury's premium outboard. Quieter, smoother, and more refined than Pro XS at comparable HP. Available in V8, V10, and V12 configurations. Joystick Piloting works with Verado.
For most Ontario fishing-focused center consoles, Verado is more motor than the job requires and adds significant cost. We recommend Verado for twin-engine setups where the ride quality and noise difference actually matters across multiple hours at cruise.
Best for: Premium builds, twin-engine setups, buyers prioritizing ride quality and quiet operation.
Recommended motor by boat size
17 to 19 ft trailerable
Motor: Mercury 90 to 115 FourStroke, or 115 Pro XS if you want more hole-shot.
Performance: 35 to 42 mph two-up.
Use case: Bay of Quinte walleye, sheltered Lake Ontario days, river running.
20 to 22 ft trailerable
Motor: Mercury 200 Pro XS V6 (3.4L) is the sweet spot. 150 Pro XS works on the lighter 20 ft hulls.
Performance: 45 to 55 mph two-up with the 200 V6.
Use case: Lake Ontario salmon, Bay of Quinte, full-day trips.
This is the most common Ontario center console application.
23 to 25 ft single engine
Motor: Mercury 250 Pro XS V8 (4.6L) for fishing; 300 Verado V8 if quiet ride at cruise matters more than hole-shot.
Performance: 50 to 60 mph two-up.
Use case: Lake Ontario salmon tournament days, bigger-water Bay of Quinte.

25 to 28 ft twin-engine
Motor: Twin 250 Pro XS V8 for performance; twin 300 Verado V8 for premium ride.
Performance: 55 to 65 mph two-up.
Use case: Offshore Lake Ontario, premium fishing or family use.
If you are buying a 25 to 28 ft center console in Ontario and you plan to run it in October salmon season, twin engines are not a luxury.
28+ ft (rare in Ontario)
Motor: Triple Mercury 350 Verado V10, or triple/quad 400+ Verado V10 for peak performance.
Use case: Top-tier Great Lakes setups; most of these boats are U.S. imports.
Single vs twin: how to actually decide
1. What the hull is rated for. Most boats are designed for one configuration. Do not fight the manufacturer's bracket rating.
2. How far offshore you run in worst-case conditions. If your longest trip is 5 to 8 km offshore on Lake Ontario on a calm summer day, a single is fine. If you are running 25 to 30 km offshore in October targeting salmon, a twin gives you get-home redundancy when one motor quits far from shore.
3. Whether you want Mercury Joystick Piloting. If docking precision matters to you, Joystick Piloting is a real quality-of-life upgrade. It requires twin engines minimum.
The cost difference is real. A twin-Mercury 250 Pro XS V8 setup is roughly 1.7x the cost of a single 300 V8 of equivalent total HP. For most Ontario trailerable buyers, single is the right answer.
Mercury Joystick Piloting: what it actually does
Joystick Piloting controls thrust direction across both motors, letting you walk the boat sideways into a slip at low speed without using the wheel. In practice, it is genuinely useful for:
- Tight marina slips with crosswind
- Docking single-handed
- Trent-Severn locks where you are holding position against current
Requirements:
- Twin or more matched Mercury outboards (same family, same HP, same generation where possible)
- Electronic shift and throttle (no mechanical cable)
- Compatible Mercury motors from 2014 onward
Cost: Roughly $4,000 to $7,000 CAD added to a twin rigging, depending on motor generation and existing controls.
Rigging details that matter for center consoles
Prop selection: Aluminum props on a 200+ HP center console are a false economy. Mercury Bravo 1 FS, Bravo 1 XS, or Fury 4 in the right pitch is the standard starting point for V6/V8 power. Budget $700 to $1,300 CAD for the prop on a fresh repower.
Hydraulic steering: Required for V6 and V8 motors. SeaStar Pro hydraulic is our default.
NMEA 2000 backbone for twins: If you are running twin motors, plan a proper NMEA 2000 backbone for chartplotter-engine integration and Joystick if applicable.
Transom bracket check: Modern center consoles use transom brackets that move the motor 12 to 30 inches aft of the transom. Verify bracket rating before we quote a motor size.
Spring commissioning: Center consoles tend to be stored covered, not shrink-wrapped. Annual pre-launch service is worth $400 to $600 and will prevent a $4,000+ cooked impeller from ruining your first week of salmon season.
Why Ontario center console buyers come to us
We have been a Mercury dealer on Rice Lake for decades. Center-console repowers are a real part of our shop volume because we know the Ontario use case: Lake Ontario salmon, Bay of Quinte walleye, the Bay of Quinte salmon, and the occasional Georgian Bay day trip.
We do not oversell Verado to fishing-focused buyers. Pro XS is the right motor for most Ontario fishing-focused center consoles. We recommend Verado when the premium is actually justified by how the boat is being used.
Pickup is at Gores Landing. That is not a downside, it means your motor was rigged by a tech who has put a lot of Lake Ontario and Bay of Quinte center consoles in the water.
