Quick answer: Honda outboards are excellent in the 9.9-50 HP class. Switching to Mercury makes sense for two reasons: Ontario dealer-network access (Mercury has 3x more service points) and HP-class match above 60 HP. Brand swap costs $1,800-$3,500 extra in rigging (controls, gauges, harness, prop). Email info@harrisboatworks.ca with your Honda specs for a same-day side-by-side quote.
Honda BF outboards have a loyal following in Ontario, particularly in the 9.9-50 HP class for small fishing boats and tenders. The motors are quiet, fuel-efficient, and built to a high standard. We don't sell Honda at HBW (we're Mercury Platinum), but we respect the brand. This guide is the honest case for switching from Honda to Mercury, where it makes sense, and where it doesn't.
Why customers switch from Honda to Mercury
The Honda-to-Mercury swap is less common than Yamaha-to-Mercury in Ontario because Honda has a smaller installed base here. The customers who do switch have one of three reasons.
Service network density. Honda has roughly one-third the Ontario dealer footprint of Mercury. In the GTA proper this isn't a big deal, but in the Kawarthas, Trent-Severn corridor, Bay of Quinte, and rural cottage country, the nearest Honda dealer can be 90+ minutes away. Mercury Platinum dealers are typically 30-45 minutes away in the same areas. For mid-season service emergencies, the difference matters.
HP class match for repowers above 60 HP. Honda's BF lineup tops out at 250 HP (BF250). Mercury offers everything from 9.9 portable to 600 HP Verado V12. If your next repower is in the 250-600 HP range or you're moving to a tritoon that wants Pro XS, Mercury has the lineup match Honda can't offer.
Dealer service experience. This is subjective, but we hear it: customers who've had a hard time getting Honda service slots in Ontario sometimes switch to Mercury because HBW (and other Platinum dealers) have invested in service capacity. Hours-on-the-water lost to service queue is a real cost.
What changes vs what stays the same
Honda and Mercury both use different proprietary control architectures. None of the Honda-specific rigging carries over. The cost of switching is in the rigging, not the motor.

Hydraulic carries over; cable steering may need replacement at higher HP. |

Carry over. |
The cost premium for switching brands (vs same-brand repower) is roughly $1,800-$3,500 depending on whether you have mechanical or digital controls and how integrated your existing dash is.

The brand-swap premium for Honda customers is slightly lower than Yamaha customers because Honda gauges tend to be analog-friendly and integrate slightly more easily with replacement Mercury gauges than Yamaha Command Link does.

Where Honda genuinely wins (we're honest about this)
We don't sell Honda. We DO try to give honest advice. Here's where Honda is the right call and a switch to Mercury doesn't make sense.
Small kicker on a fishing boat (9.9-25 HP). Honda BF9.9, BF15, BF20, BF25 are all excellent kickers. Famously quiet, famously fuel-efficient. If your boat is already rigged for Honda and you're happy with kicker performance, switching to Mercury ProKicker (which IS also excellent) gives you a marginal improvement at a real rigging cost. Stay with Honda.
Stable boat-and-motor pairing for cottage daily use. Honda BF lineup matched to a 16-18 ft aluminum or a small pontoon for cottage cruising is a known-good combo. If you've owned the Honda for 5+ years with zero issues and your usage pattern is stable, the swap is hard to justify.
Easy local Honda dealer. If your nearest Honda dealer is reasonable and you have a relationship there, the dealer relationship is worth more than the brand swap. Stay.
Honda's fuel economy advantage at trolling RPM. Honda BF motors have a small but real edge in trolling-RPM fuel burn vs equivalent Mercury motors in the 9.9-30 HP class. For full-day trolling applications (Bay of Quinte salmon, slow walleye trolling on Rice Lake), this can add up. Mercury has closed most of the gap but Honda still has a slight edge at very low RPM cruise.
Where the switch to Mercury wins
You need 60+ HP and your nearest Honda dealer is far. Once you're above 60 HP, the service-network argument starts mattering more because the motor is doing more work and parts inventories at smaller dealers thin out. Mercury Platinum dealers are typically better-stocked.
You're going above 250 HP. Honda tops out at BF250. If you want 300 HP, 400 HP, or 600 HP, Mercury Pro XS / Verado is the only path.
You want Joystick Piloting on a multi-engine setup. Honda's iST joystick exists but Mercury's joystick integration is more mature and works with a broader range of multi-engine configurations.
You want Pro XS performance. Honda doesn't have a direct Pro XS equivalent. If you're a bass fisherman or runabout owner wanting Pro XS aggression, Mercury is the only call.
Repower planning + warranty. Mercury Canada offers 3 years limited + 3 years corrosion concurrent. Honda offers 5 years limited (some markets). Verify current warranty terms before committing because Honda's standard warranty length has historically been a Honda advantage and may still be.
What we see at HBW
A few patterns from Honda-to-Mercury conversations specifically.
The first pattern: customers in the 9.9-25 HP range almost always stay with their Honda. The brand premium to switch isn't worth it for kicker applications. We tell them this honestly. Honda makes great small motors. Stay.
The second pattern: customers in the 40-60 HP class are the gray zone. The brand-swap cost is $1,400-$2,200 on top of the motor. The performance delta between current Honda BF50 and Mercury 50 FourStroke is small (within 1-2 MPH top, within 5% fuel burn). The decision usually comes down to local dealer access and personal preference.
The third pattern: customers above 90 HP make the switch more often. Service capacity matters more on bigger motors. Parts inventory matters more. Mercury's Ontario footprint advantage compounds at this HP class.
The fourth pattern, specific to the Rice Lake / Kawarthas region: cottage owners who've had Honda dealers consolidate or close in their nearest town often switch to Mercury reluctantly. They're not thrilled with the swap cost but the service experience drives the call. We're honest with them that the swap is mostly about dealer access, not motor performance.
The fifth pattern: tournament bass anglers and Pro XS curious customers. The Honda lineup doesn't compete in the high-performance bass-boat segment. Anyone who needs that level of acceleration and top speed isn't really cross-shopping Honda vs Mercury; they're shopping Pro XS vs Yamaha SHO. Honda doesn't enter the conversation.

Common mistakes (the things we push back on)
When to switch + how to start
The honest framework:
- Stay with Honda: 9.9-25 HP kicker/portable applications; reliable Honda with low hours; close to a working Honda dealer; fuel-economy-sensitive trolling use case; happy with current setup.
- Switch to Mercury: 60+ HP and remote from Honda service; need 300+ HP; want Pro XS performance; planning Joystick Piloting on multi-engine; current Honda is tired AND closest Honda dealer is far.
