PISTONS Flat Top Set/4 Mercruiser Volvo-Penta 140HP w/Chevy Marine 3.0L 181 020

This item is for four (4) .020 in. over bore Sealed Power hypereutectic flat top pistons for Mercruiser and Volvo-Penta 3.0L (181ci) 140hp 4-cylinder engines. P/N (4) H897CP-020. These are the later model flat top pistons. The early model engines require dish top pistons; which we have on eBay as well.

If you're looking for pistons with an unbeatable combination of performance and value, then Sealed Power hypereutectic pistons are for you. These pistons are manufactured from aluminum alloy that contains 16 percent silicon for greater strength and wear resistance. They're also molded in the latest permanent-mold technology to ensure the precise fit and tight bore clearances that today's top engine builders demand. Hypereutectic pistons are ideal for use in high performance street, bracket, and oval track racing—and will work perfectly with normal ring end gaps.
