I bought two 7.4l Chevy mercruiser 350hpmonths and 24hours of run time one motor went because of the GLMORE manifold gasket on the exhaust failed sending saltwater into the motor.After tear down the motor had cylinder bored at over and the rest were overThe cause of the gasket failure was a repaired exhaust manifold.It was welded and ground down but the surface was not decked (flat,level,even...) and apparently not new.In general various bolts were miss matched or not appropriate for the marine engine.I would not recommend anything from this company
