I did a compression checo and all 4 cylinders were between 165 and 180 psi so I feel good about that. I found a small visible crack in the exhaust manifold under the bottom that is dripping some water.
My question is had anyone seen this style manifold leak in the inside and get water in a cylinder as it is running?
The boat runs good up to about 2k rpm but after that is starts missing and busting up with the occasional backfire. New fuel filters and plugs wires and coil. I need to check fuel pressure now, anyone have an idea of what range it should be in?

Does that need to be check while boat is in water and under way because that is only time symptoms arise or will on the hose do?
