HP1 Moroso Performance Oil Filter, Stock Ford & Chrysler 

Hardin Marine, Stock Ford & Chrysler Moroso Performance Oil Filter - 3/4"-16 Thread

Take note marine engines are subjected to extreme loads caused by high rpm runs for long periods of time subjecting your filtering situation to that of a racing vehicle. Racing filters are designed to flow more oil at any given rpm and that's what a marine engine needs most not filtering for thousands of miles like a car. Treat your engine to the best filters available and it won't let you down when you need it most.
