Performance & Practical Benefits

The 817275Q05 kit restores full water pressure through your engine’s cooling system. Its upgraded impeller and precision-fit seals provide consistent flow to keep temperatures stable at every speed. This is especially important if your boat has been run in sandy or silty conditions that can wear down the pump housing.

The new gaskets and fittings prevent leaks and maintain high efficiency in the pump chamber, giving you strong, steady flow even after years of use. Regular replacement ensures your drive stays healthy and your boat performs at its best.

Why Buy OEM

Mercury’s OEM parts are engineered for real-world marine use — exact fit, proper sealing, and proven endurance. Aftermarket kits might use cheaper materials or imprecise gaskets that shorten pump life and reduce cooling performance.

A genuine Quicksilver repair kit gives you the same quality and reliability your sterndrive had when it was new — built to fit right, last long, and protect your investment.
