GM 4.3 Marine Engines

ATK is a leading manufacturer of marine engines that are made with maximum performance and long term durability in mind. The engines are designed and built specifically for boating and all the rigors and conditions marine engines face. ATK takes pride in the fact that there are over 150 processes involved in remanufacturing each ATK engine including the GM 4.3 Marine Engine.

Your boat is only as good as the engine in it. Without an engine in good working order, you might as well not have a boat at all. You will be stuck sitting at the dock. The GM 4.3 Marine Engine has been used in marine applications since 1986 and designed to meet or exceed O.E Specifications. The engine blocks and cylinder heads are magnafluxed to determine if there are any cracks. Camshafts bearings are examined to ensure accurate center-to center clearance and precision ground or replaced to maintain the O.E. profile. Pistons and rod assemblies are blanched to minimize engine vibration All bearings, timing belts, chains, gears
