Quick answer: A Honda-to-Mercury switch is worth comparing when the Mercury product family, local authorized-service route, or rigging plan fits your boat better. It is not an automatic upgrade. Honda currently builds through the BF350 V8; Mercury's Canadian lineup continues above 350 HP. Keep a good Honda kicker if it still does the job. Compare the current motor price and a written installed quote instead of relying on generic ranges.
Quick answer
Honda outboards are excellent in the 9.9-50 HP class. A switch to Mercury can make sense when the local authorized-service route or the required Mercury product family fits better. Brand-swap rigging depends on controls, gauges, harness, propeller, steering, and the existing dash, so use a written side-by-side quote rather than a generic range.
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 Premier), 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. Before pricing a brand switch, work through our repair, repower, or sell decision guide to confirm repower is the right call at all.
Why customers switch from Honda to Mercury
At HBW, Honda-to-Mercury enquiries are less common than Yamaha-to-Mercury enquiries. The Honda owners who do ask us about switching usually have one of three reasons.
Service access. Dealer networks change. Use the current Mercury dealer locator and Honda Marine dealer locator, confirm that the location services the exact model, and compare the real route from where the boat lives. Do not rely on a generic network ratio or drive-time claim.
HP class and engine-family match. Honda Marine Canada currently lists the BF350 V8. Mercury Canada lists FourStroke models through 300 HP, Verado families from 250 to 425 HP, and the 600 HP V12. Above 350 HP, or when the job calls for a Mercury-specific Pro XS or Verado configuration, the available product family can decide the comparison.
Dealer service experience. This is local and personal. A dependable nearby Honda dealer can be a good reason to stay with Honda. A customer who wants HBW to own the repower and ongoing Mercury service may value that relationship more than the badge comparison. Compare the actual support route, not a province-wide slogan.
What changes vs what stays the same
Honda and Mercury use different control and engine-data systems. Some Honda-specific rigging must be replaced, while some boat-side hardware may stay after inspection. The installed quote has to separate what carries over from what changes.

What a Honda-to-Mercury swap costs in Ontario
The motor is only one line of a brand-swap quote. Depending on the boat, the job can also require a control box, cables or DTS harness, gauges or VesselView, a Mercury propeller, steering changes, battery work, removal, installation, and on-water testing when seasonal conditions allow. The Honda model, current rigging, dash, hull, and chosen Mercury package decide which lines apply.
Use the live Mercury pricing reference for current motor-only prices. Then build a quote or send HBW the Honda cowl plate and helm photos for a written installed proposal. Static tables age badly and cannot tell whether your steering, fuel system, batteries, or instruments can stay.
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, and BF25 are established small-motor choices. If your boat is already rigged for Honda and you are happy with its kicker performance, switching brands is a new rigging decision, not a guaranteed improvement. Keeping the Honda can be the sensible answer.
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.
Where the switch to Mercury wins
The local Mercury support route is better for the boat. If HBW is the practical service destination and the nearest suitable Honda support is not, that can matter more than a paper specification. Check the current locators and the exact services each dealer provides.
You're going above 350 HP. Honda Marine Canada's current line reaches the BF350 V8. Mercury Canada's Verado range tops out well past that; check the current model lineup before you count on a specific horsepower. That is a real lineup difference, but the hull rating, transom, steering, controls, and use case still decide whether any of those motors belongs on the boat.
You want a Mercury SmartCraft or Joystick configuration. Controls and compatibility are package-specific. If those Mercury systems are part of the goal, quote the entire control and steering package rather than comparing engines alone.
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's limited warranty length varies by market. 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. If the current Honda is healthy and the boat already works, a badge change alone is a weak reason to repower. The decision usually comes down to hull fit, current rigging, local dealer access, and the written side-by-side quote.
The third pattern: on larger repowers, controls, steering, gauges, prop selection, and service ownership become a larger part of the decision. That is where a complete installed proposal is more useful than a motor-only comparison.
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 or portable applications; a healthy Honda that already fits the boat; a good local Honda dealer relationship; or a setup that is doing the job without a clear reason to change.
- Switch to Mercury: the local Mercury service route is the better fit; you need a Mercury-specific Pro XS, Verado, SmartCraft, or Joystick package; you need an option above Honda's current 350 HP range; or the written installed comparison favours the Mercury repower.
To start a quote at HBW: email cowl plate photos of your Honda plus photos of your helm controls and gauges to info@harrisboatworks.ca. We will review the configuration and prepare a side-by-side Mercury quote or ask for any missing information.
