SERVICE KIT 135-175HP OPTIMAX (69000Z03)

The SERVICE KIT 135-175HP OPTIMAX is a comprehensive OEM maintenance kit designed specifically for Mercury 135HP to 175HP OptiMax 2-Stroke direct-injected outboard engines. This kit includes all essential components required for regular servicing, ensuring your engine continues to deliver the high performance, fuel efficiency, and reliability OptiMax models are known for.

Servicing your engine at scheduled intervals is critical to maintaining top-end performance and avoiding premature wear or unexpected breakdowns. The SERVICE KIT 135-175HP OPTIMAX simplifies this process by packaging all the necessary parts into one convenient, factory-approved kit. Inside, you’ll find a water pump impeller and housing, fuel filter, compressor strainer, spark plugs, drain gaskets, and a full set of seals and o-rings—all engineered to Mercury’s exacting OEM specifications for durability and perfect fit.

A key component in this kit is the water pump impeller, which ensures optimal water circulation throughout the engine’s cooling system. Over time, impellers degrade or lose flexibility, which can lead to reduced cooling efficiency and overheating. Replacing the impeller at regular intervals helps maintain engine temperature and extends the life of your OptiMax outboard.

The included fuel filter is designed to protect your direct fuel injection system from contaminants that could cause clogging or poor combustion. Keeping your fuel system clean helps sustain smooth engine performance, better fuel economy, and reduced emissions. The compressor strainer is another critical part—keeping your air compressor protected from debris that could impair operation or affect combustion.

The spark plugs provided in the kit ensure strong, consistent ignition across all RPM ranges, supporting reliable starts, smooth idling, and responsive throttle control. All included gaskets and seals are marine-grade, designed to resist salt, corrosion, and pressure for long-term leak protection and engine integrity.

Whether you’re a professional marine technician or a boat owner maintaining your own engine, the SERVICE KIT 135-175HP OPTIMAX provides everything you need in one box to perform a thorough and correct service—saving time, eliminating guesswork, and ensuring top-level care for your engine.

Trust the SERVICE KIT 135-175HP OPTIMAX to deliver long-lasting performance, factory-quality parts, and the confidence to take on any adventure with your Mercury OptiMax outboard.
