The 150HP EFI FourStroke SERV KIT-100 HRS is a factory-engineered maintenance solution designed specifically for Mercury 150HP EFI FourStroke outboards. Built to support the 100-hour service interval, this genuine OEM kit includes all the essential components needed to maintain top-tier performance, fuel efficiency, and long-term reliability in one convenient package.
Performing scheduled maintenance at 100-hour intervals is crucial to keeping your outboard running at its best. This service kit eliminates the guesswork by including only components that meet Mercury’s strict quality and durability standards. Inside, you’ll find a high-quality seawater pump impeller, oil filter, fuel filter, spark plugs, drain screw gaskets, and other vital seals and o-rings—everything required to complete your routine service with confidence.
The water pump impeller, a key item in the cooling system, ensures continuous water circulation to prevent overheating. Worn impellers can cause engine temperature spikes and reduce performance. Replacing it at regular intervals safeguards the engine against thermal stress and improves cooling reliability.
Equally important are the oil and fuel filters, which capture harmful debris and contaminants before they can impact internal engine components. Clean filtration extends the lifespan of engine parts and preserves optimal fuel combustion. The included spark plugs support consistent ignition and clean, efficient engine starts every time you hit the throttle.
Using the 150HP EFI FourStroke SERV KIT-100 HRS ensures your maintenance routine is not only easier but more precise. Each part in the kit is made to exact factory dimensions, guaranteeing proper fit and compatibility with 150HP Mercury EFI FourStroke models. Whether you perform your own servicing or rely on a marine technician, this all-in-one kit saves time and removes any uncertainty from your maintenance schedule.
Designed to withstand tough marine conditions, the components in this kit help protect your outboard from corrosion, leaks, and avoidable wear. Maintaining your engine properly with the right parts reduces the risk of sudden breakdowns, improves fuel economy, and extends the life of your investment.
When it’s time for your 100-hour service, trust the 150HP EFI FourStroke SERV KIT-100 HRS to deliver OEM-grade protection and performance, ensuring your engine is ready for whatever your next adventure on the water brings.
