Warranty & Maintenance
Limited Warranty
World-class marine products backed by world-class warranties. We stand behind everything we build, and we go the extra mile to make sure your Mercury experience is the best it can be – on the water and off.
Mercury Product Protection
Mercury Product Protection is an extended service contract for your Mercury engine that covers certain expenses caused by defects in materials and workmanship after the Mercury Limited Warranty expires.
Maintenance
Whether you keep your outboard at a remote outpost or in your garage, we’ve made maintenance easier. Our maintenance-free camshaft requires no regular service and no valve leash adjustments. Ever. For the life of the engine. Changing crankcase and gearcase oil is a snap, too. The oil-filter drip tray (on EFI models) and easy-drain design minimize messes. And the gear lube will fully drain from any tilt position. Less hassle leaves more time for fun.
