Built To Last! Remanufactured Marine Engines with Nationwide Parts & Labor Warranty
Speed Pro pistons, made of a special hypereutectic alloy and coated with moly, are less prone to scuffing on cold starts and virtually eliminate ring groove pound-out.
Positive intake seals meter the oil to the valve stems to reduce oil consumption and help prevent abnormal combustion.
Melling double roller, heavy-duty timing chains have passed GM's 400-hour "dock test." No car-type link chain has ever passed this test.
Brass freeze plugs will never rust or corrode like the standard steel ones found in most other engines.

Heavy-duty valves with chrome-plated stems minimize wear to insure longer life and better performance.
