Dealing with fuel delivery issues on your Mercruiser or OMC engine? This replacement fuel pump (part number 86234A4) might be your solution! It cross-references with several other common part numbers including 18-7278, 60032, 985602, and others, making it compatible with a wide range of marine engines. Fits Mercruiser 140 (3.0L), 470/485/488 (3.7L), and 160/165/200 (4.1L) models from the late 60s through 80s, plus OMC 100/110/120/140 engines with 2.5L and 3.0L configurations. If your engine's struggling to start, losing power at higher RPMs, or just not running smoothly, a worn-out fuel pump could be the culprit. This direct replacement installs without modification and restores proper fuel pressure to keep your engine running strong. Marine engines work hard, and after years of service, the original fuel pump diaphragm and valves can wear out. Before ordering, absolutely verify your engine model, year, and existing part number to ensure compatibility - marine engines have subtle differences between years that matter. This is one of those maintenance items that can dramatically improve your boat's reliability on the water. Don't get stranded by fuel delivery problems - keep a spare on board or replace that aging pump before it fails completely!
