Technical Tips

This engine includes all of the necessary parts in order to adapt a pre-1990 3.0L engine to a new 1 piece rear main seal GM marine 3.0L engine. Includes flywheel, coupler, manifold gasket, distributor, ignition coil, and fuel pump.

Note: The new distributor on this engine requires that the fuel pump be mounted with the filter on the bottom (select this link to view image of old style "upside down" mounted fuel pump.) Also the fuel pump outlet will be pointing towards the back of the engine and therefore it requires using a marine grade fuel hose to run from the pump up to the carburetor.

Includes an Up To 12 month limited warranty.
