The 3.0L MerCruiser is fuel-efficient with sequential multi-port fuel injection that precisely meters the air-to-fuel ratio, ensuring efficient operation any time the engine is running. The Emissions Control Technology (ECT) system works in tandem with the CPU to keep emissions in check. The result is better gas mileage and a longer range.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eOver time, however, these MerCruiser outboards degrade due to harsh aquatic environments, heavy usage, and the lifespan of components.

Check to see if the pump runs properly and that your bilge wiring, discharge hose, hose clamps, and thru-hull fitting are all in great shape. If your boat’s freshwater system was winterized, be sure to fill your tanks and flush antifreeze from the system, and dispose of it per the manufacturer’s recommendations.
