Overview

Meet a reliable replacement fuel pump designed for legacy marine engines. The YRANZO unit is tailored for older Mercruiser and Volvo Penta configurations, offering a compatible, cross-referenced option to help maintain steady fuel delivery during daily runs or weekend adventures. While it won’t alter your engine’s performance, it presents a practical path to keeping essential fuel circulation in workhorse setups that power days on the water.

Engine compatibility and fit

This pump is built to support a range of Mercruiser and Volvo Penta applications, including Mercruiser 165, 170, 180, 181, 190 and 225 HP units, spanning 2.5L and 3.0L displacements, along with 3.7L engines from the 1984–1993 window. For Volvo Penta, it covers 181 with 3.0L engines from 1995–2001. In short, it targets classic combinations that boaters may still rely on.
