Quick answer: Your Mercury warranty starts the day the motor is rigged and registered. Current FourStroke outboards carry a 3-year factory limited warranty for recreational use, and until June 14, 2026 every new Mercury at Harris Boat Works ships with 7 years of factory-backed coverage as an HBW Exclusive. We're a Mercury Platinum dealer, so the warranty is registered correctly and claims are handled in-house.
Your Mercury warranty starts the day the motor is rigged and registered, here's what it covers.
A Mercury outboard repower comes with a factory warranty. How long that warranty runs, what it covers, and how it's registered depends on the motor model and how the installation is done. This page explains the key facts clearly.
We are a Mercury Marine Platinum dealer. That matters for how warranty claims are handled, we explain why below.
What Mercury's factory warranty covers
Mercury's warranty covers defects in materials and workmanship on the outboard motor. This means: if something fails because of how the motor was made or assembled, Mercury covers it.
Current Mercury FourStroke outboards carry a 3-year factory limited warranty for recreational use. Right now there is a bigger window: every new Mercury outboard at Harris Boat Works comes with 7 years of factory-backed coverage as an HBW Exclusive, available until June 14, 2026. Straight Mercury coverage, no third-party contract.
The warranty covers:
- The engine itself, internal components, powerhead, fuel system
- Factory-installed parts
The warranty does not cover:
- Normal wear items (impellers, anodes, spark plugs, lower unit seals after reasonable use)
- Damage from running the motor out of water, overheating due to blocked cooling, or improper operation
- Damage from using non-recommended fuel or oil
- Damage from modifications or installation not performed to Mercury's specifications
What "rigged by a Mercury dealer" means for your warranty
Mercury's warranty is tied to proper installation. When a repower is done by a certified Mercury dealer, using Mercury-approved rigging standards, correct shaft length, proper controls, and correct mounting, the warranty is registered correctly and there are no gaps.
When a motor is purchased elsewhere and self-installed, or installed by a shop that isn't a Mercury dealer, warranty claims can be complicated by questions about whether the installation met Mercury's standards.
We're a Mercury Platinum dealer. Platinum is Mercury's top dealer service tier. For warranty work, that means factory-trained technicians, direct access to Mercury technical support, and claims submitted by the same shop that rigged your motor. Every motor we sell and rig is registered under your name with Mercury Marine from day one.
Extended warranty options
Mercury offers extended warranty programs beyond the factory coverage period.
Mercury's extended-coverage program is Mercury Product Protection (MPP). Terms and pricing vary by model and are quoted at the time of sale. And until June 14, 2026, the HBW Exclusive 7-year coverage described above applies to every new outboard we sell, which answers the question for most current buyers.
Extended warranty coverage is easiest to add at the time of the repower, before the motor is first registered. Ask about this when you're building your quote.
Break-in period: what it is and why it matters for warranty
Mercury FourStroke outboards have a break-in period, a set of operating hours during which you avoid running the motor at wide-open throttle continuously.
The exact procedure is in your owner's manual and varies by model, but the shape is consistent: vary your throttle and avoid sustained wide-open throttle through the first 10 hours, with the gentlest treatment in the first hour. We walk you through your motor's specific procedure at pickup.
The break-in period is not a formality. Running a new motor hard before the internal components have seated properly can cause wear patterns that affect performance and, in some cases, can affect how Mercury handles a claim related to those components.
We walk every repower customer through the break-in procedure at pickup.
How to make a warranty claim
If something goes wrong with your Mercury motor during the warranty period:
- Contact us at 905-342-2153 or submit a service request at hbw.wiki/service
- We assess the issue and determine whether it falls under warranty
- If it does, we submit the claim to Mercury on your behalf and perform the work
- You pay nothing for covered warranty repairs, Mercury pays the dealer
Do not attempt to repair or modify the motor before contacting us. Unauthorized repairs can complicate a warranty claim.
What changes if you move to a different Mercury dealer
Mercury warranty is tied to the motor's serial number, not to the dealership where it was sold. If you move or sell the boat, the warranty follows the motor. Any authorized Mercury dealer can perform warranty work.
