Hey guys, my buddy picked up his first jet boat recently and we've got a few rookie questions. A few buddies and myself got together and thrashed on it for a weekend and got it on the water. Now we just need to fine tune it and get it right. One of our buddies knows his way around a jet boat so he guided us through getting it ready but he lives 5 hours away and it can be hard getting advice over the phone.
The boat is a Sabrejet with an olds motor and a Berkeley pump that he picked up for pretty cheap on CL. We had to put the intake and new carb on it to fire it for the first time. It fired right up and sounded decent. After we ran it we noticed it was leaking around the seal that seals the pump to the transom. I also noticed some smoking coming through the valve cover breathers and, what I believed to be excessive smoking from the through-transom exhaust.
My questions: What needs to happen for us to replace the transom/pump seal? Full pump removal? And what would cause smoking through the valve cover breathers? I was leaning towards valve seals.
