Quick answer: Mercury's standard Canadian warranty is 3 years on most FourStroke models. Bonus warranty coverage applies only when an eligible promotion is active; see current promotions. Coverage requires eligible purchase, proper registration, maintenance according to the applicable manual, and service records.
The short version: every new Mercury outboard sold in Canada comes with a 3-year limited warranty AND a 3-year corrosion warranty, both starting the day you buy it, both ending the same day three years later. They're concurrent, not stacked. Anyone telling you you have "six years of coverage" is reading the brochure wrong.
We're a Mercury dealer in Ontario since 1965. We do warranty work in our shop every week. This is the version of the warranty conversation we have with customers when they're buying a new motor or wondering if it's worth extending.
The Two Standard Warranties (Both 3 Years, Both Start Day One)
Every new Mercury outboard sold in Canada includes:
1. Mercury 3-Year Limited Warranty. Covers manufacturing defects in the motor, powerhead, gearcase, ignition, electronics, fuel system. If something fails because of a defect (not abuse, not neglect, not wrong oil), Mercury covers parts and labour at any authorized Canadian dealer.
2. Mercury 3-Year Corrosion Warranty. Covers structural corrosion of the motor, hull-side surfaces, mounting bracket, exterior components. Important to understand: this runs concurrently with the limited warranty, not after it. Both clocks start the day you buy. Both stop on the same day three years later.
This is the single most-misunderstood part of Mercury's warranty. Some sales pitches frame it as "3+3 = six years of coverage." It isn't. You get three years total, with two different things being covered during those three years.
That said, three years of full Mercury factory coverage is genuinely excellent for the marine industry. Most competing brands offer two to three years on similar terms. Bonus warranty promotions sometimes extend that base for eligible purchases, but those offers are time-limited. See current promotions and our Mercury outboard warranty guide for the current position.
What's Actually Covered
The 3-year limited warranty covers manufacturing defects in:
- Powerhead components (cylinders, valves, ignition, EFI)
- Gearcase internals (gears, shafts, seals)
- Electrical and electronic systems (SmartCraft module, charging, sensors)
- Fuel delivery system (injectors, fuel pump, lines)
- Outboard structure as designed and built
The corrosion warranty covers structural corrosion that wasn't caused by external damage or abuse:
- Hull-side surfaces of the motor
- Bracket and mid-section
- Trim system housing
- Anodes are wear items and excluded (you replace those yourself)
What's NOT covered under either warranty:
- Wear items (impellers, anodes, spark plugs, propellers, fuel filters, oil)
- Damage from collision, grounding, or operator error
- Damage caused by improper installation or setup
- Damage caused by contaminated fuel or fuel outside Mercury's published specification; current Mercury guidance permits gasoline containing up to 10% ethanol
- Damage from running the wrong oil grade or skipping break-in
- Modifications, racing use, or commercial use on a recreational-spec motor
The phrase "improper installation" matters. Mercury can exclude damage caused by an installation or setup error. This is one reason we strongly recommend having any new Mercury rigged at an authorized Mercury dealer: the predelivery work, registration, and rigging record are documented if a related problem appears later.
Extended warranty decision
Should you buy Mercury Product Protection?
Platinum Product Protection can bring eligible coverage to a maximum of 8 combined years. The honest answer depends on the exact price, how long you keep the boat and how much repair-cost certainty matters to you.
Take MPP extended coverage
- ✓You're financing the motor over 5+ years
- ✓You plan to keep the boat 7+ years
- ✓You run meaningful seasonal hours or tow regularly
- ✓Peace of mind matters more than the upfront cost
Price the eligible Platinum term
Factory coverage is enough
- ✓You're paying cash
- ✓You typically flip boats every 3 to 5 years
- ✓You run a modest seasonal schedule
- ✓You service religiously and keep records
Stick with the 3-year factory
When in doubt:Compare the exact Platinum price with your ownership horizon. Transfer is available to a subsequent recreational-use buyer, but Mercury's timing, eligibility and inspection terms apply.
Mercury Product Protection Platinum. The Extended Service Contract
If you want coverage after the applicable Mercury limited warranty, Mercury offers Mercury Product Protection (MPP), an optional extended service contract. HBW normally quotes the Platinum plan because it is Mercury's broadest Product Protection tier, covering eligible mechanical and electrical failures. Platinum is the Product Protection tier. Mercury Premier describes a dealer tier, not a Product Protection plan.
The current Canadian Platinum provisions and your motor's serial record govern eligibility. Important points:
- Factory limited warranty and paid Product Protection cannot exceed 8 combined years.
- Product Protection must be purchased before the applicable factory limited warranty expires. Mercury's Canadian terms apply a surcharge when it is purchased after the first factory-warranty year.
- The motor must meet Mercury's age, hour and recreational-use rules. Current Canadian terms specify the current model year plus four previous calendar years and fewer than 500 accumulated engine hours.
- A transfer to a subsequent recreational-use buyer must be submitted within 30 business days and remains subject to Mercury's eligibility, documentation, inspection and fee requirements.
- Claims are made through an authorized Mercury dealer. Mercury approval and the Canadian contract terms apply.
- Platinum covers the mechanical and electrical parts specifically listed in the contract. Maintenance, normal wear, corrosion, accident damage, abuse, commercial use and unauthorized modifications are excluded.
We confirm the available term against the serial record and any applicable promotion before registration. Current Mercury promotions are maintained separately because included coverage can change how many paid Product Protection years are needed.
What Platinum costs: HBW publishes the exact Canadian rate card by horsepower band and purchased term. As verified July 17, 2026, a five-year Platinum plan is $2,077 CAD before HST for 75-149.9 HP and $6,964 CAD before HST for 200-299.9 HP. See the maintained Mercury Product Protection prices and estimator for every band and one- through five-year term.
Is it worth it? It can be reasonable when you plan to keep the motor beyond the factory-warranty period, finance over a longer term or want predictable exposure to a covered mechanical or electrical failure. It can be unnecessary for a short ownership horizon or when you are comfortable carrying repair risk yourself. Use the exact price, not a generic horsepower rule.
Transferability can also be useful at resale, but it is a documented process, not an automatic promise of a higher selling price.

Buying a Used Mercury. Does the Warranty Transfer?
Mercury's limited-warranty and Product Protection transfer rules are not identical. Mercury's Canadian limited warranty allows unexpired pleasure-use coverage to transfer to a subsequent owner when the product is properly re-registered. Commercial-use coverage is not transferable. For Product Protection, the current Canadian Platinum provisions allow transfer to a subsequent recreational-use buyer when the transfer is submitted within 30 business days and Mercury's eligibility, documentation, inspection and fee requirements are met.
If you're buying a used Mercury under three years old, ask the seller for:
- Original sale receipt or dealer invoice (proves warranty start date)
- MPP contract documentation (if extended coverage was purchased)
- Service records from any authorized Mercury dealer (proves no warranty-voiding work)
The serial number lets an authorized dealer check the Mercury record, but a transfer or eligibility review can still require proof of sale, owner information, and supporting documents. Do not price a used motor as though coverage is guaranteed until the serial record and paperwork have been checked.
When we do pre-purchase inspections at HBW, the warranty paper trail is part of the report. (See our Used Outboard Buying Guide for the full inspection checklist.)
What Mercury Warranty Does Not Cover
Mercury's written Canadian warranty is more specific than the phrase "voids the warranty." It does not cover routine maintenance or normal wear. It can also exclude damage caused by neglect, abuse, improper service, unsuitable fuel or lubricants, improper installation, certain untested parts or accessories, restricted cooling water, submersion, or unauthorized modification.
The practical maintenance rules are:
- Use the fluid specification in the exact manual. Current FourStrokes require an FC-W-rated marine oil in the viscosity Mercury specifies for that engine.
- Follow the model-specific schedule. For most current recreational FourStrokes, the first scheduled service is 100 hours or annually. Mercury does not publish one universal 20-hour warranty service for every outboard.
- Keep records. Mercury can ask for proof of proper maintenance when reviewing a related claim.
- Use the correct storage procedure. Damage caused by improper storage or service is not a manufacturing defect.
- Do not make unauthorized modifications or use the product for racing. Mercury's written terms identify those as termination conditions.
- Register the actual use. Pleasure and commercial coverage periods differ. The registration needs to match how the engine is used.
Using a non-OEM maintenance part does not accurately mean the whole warranty vanishes automatically. Mercury can exclude damage caused by an accessory or part it did not manufacture, sell, or test. Match the required specification, use a reputable part, and keep the receipt.
Canadian-Specific Things to Know
Warranty registration in Canada. Most Mercury dealers (HBW included) handle warranty registration at the time of sale or shortly after, so the customer doesn't typically need to do it themselves. You should receive a confirmation from Mercury Marine, ask your dealer for a copy of the registration document if you don't. If you bought the motor used or privately, contact Mercury or an authorized dealer to confirm registration status and any documentation required.
The dealer network. Every authorized Mercury dealer in Canada honours warranty work, regardless of where the motor was purchased. So if you buy in Ontario and move to BC, your warranty doesn't lapse, but the closest dealer is now four provinces away, and warranty work needs to be done at an authorized dealer.
Cross-border purchases. Mercury motors imported privately from the US do NOT have Canadian warranty coverage. This catches buyers who think they're getting a deal at a US dealer. Mercury Canada and Mercury USA are separate warranty entities, a US-purchased motor has US coverage only, and that coverage doesn't apply at Canadian dealers. If you're tempted, do the math including the lifetime cost of out-of-warranty repairs.
The HST factor. HBW's published Platinum prices are in Canadian dollars before HST. Buying later does not avoid tax, and the Canadian terms say purchases after the first factory-warranty year are subject to a surcharge. Check current promotions and have HBW verify the serial record before choosing the timing.
Why Where You Buy Matters
The motor is the same. The warranty terms are the same. What's different is the dealer.
A Mercury Premier dealer has factory-trained technicians, Mercury diagnostic access, and direct warranty-claim capability. The written warranty terms are the same across the authorized Canadian network; the practical advantage is having the registration, rigging, maintenance, and claim records handled in one place.
We've been a Mercury dealer in Ontario since 1965. Every new Mercury we sell gets registered at point of sale, documented in our service file, and supported by the same shop for the full warranty life. If something breaks, you don't have to explain who did the rigging or whether the break-in service was done, it's all in our records.
If you bought a Mercury elsewhere and want warranty work done in our shop, we can do that too, bring your purchase paperwork and we'll get the Mercury claim moving.

What we see at HBW
The warranty starts with an eligible purchase, Mercury's documented predelivery inspection, and proper registration. After that, the owner needs to follow the applicable manual and keep maintenance records. A universal 20-hour service record is not one of Mercury's published Canadian conditions.
An authorized dealer can verify registration, document the work it performs, and submit warranty claims through Mercury's network. That clean paper trail makes a claim easier to review without inventing an extra maintenance requirement.
