Re: mercruiser 3.0ltr steam power ???
Strange that an engine can run 100% and lose power on throttling up.But i would look at the intake/exhaust gasket area and expect the attaching bolts to be loose,or the manifold to be warped.i would also look at the carb base gasket as well as the exhaust bellows.i could do this,but you'd have to bring the boat to me.Then i could retire.<br /><br /><br />dreaded ($$$) dealer<br /><br />DHP
