At this displacement and power level, staying on top of the water pump impeller and thermostat service is especially important, as an overheating event on a high-output engine can cause significantly more damage than on a smaller motor. Replace the impeller on schedule regardless of apparent condition — impeller rubber degrades with age even without visible wear.\u003c\/p\u003e\u003cp\u003eFor the smaller Mercury Optimax 1.5L kit, see the \u003ca href=\"\/products\/sierra-9251-outboard-maintenance-kit-mercury-75-115hp-optimax-1-5l-2-stroke-47-9251\"\u003eSierra 9251 Kit\u003c\/a\u003e.
