Mercruiser 3.0 dumping all its oil

[Ryant10275]

So i bought a boat that needed a head gasket. Fixed that and then spent weeks tracking a shorted wire( which i eventually found) in the process of finding the short the Previous owner installed an electric fuel pump and i figured that could be the issue so i removed the electric pump and installed a mechanical back on the engine. Well yesterday i was out on the water for a while and on my way back to the launch i started hearing valvetrain noise. Got it out of the water and the hull was full of oil. After just cleaning it out I’m about 95% sure the oils is coming out where the fuel pump bolts onto the engine. What could cause this? Did i get the wrong pump? I put new gaskets in there was like 3 of them that came with the pump and i installed all 3

What though? There’s literally only one way it can go together? Should i have not put all three gaskets in or what?

What does the factory manual show

The factory manual shows one thick gasket. This did not come with one thick gasket it came with three normal thickness gaskets

Doubling up gaskets will cause a leak. Show us the pics.
