Well, is me again. The mechanic I took the boat to did install a new kit on both carburators, including the small filters. Last week I spoke to the mechanic about the problem I was having and he recommended a couple of things I should try next time I drop it in the water.
First; to start both engines and run for a few seconds before the boat goes in the water. Something to do with fuel tank pressure causing the carburator to get flooded. Second, once in the water to let the engine cover open and look for water being sprayed over the carburators.
I have not done either one of them. I discovered, after washing the engine compartment, that both front engine mounts where broke on, of course, the right engine. After removing the exhaust manifold I began working on the mounts. As I was wrenching around I noticed a fairly thick black cable broke off from somewhere under the engine. After tracing the cable I realized it was the ground cable that attaches to the starter bolt.
I replaced the mounts and re-installed the ground cable. Started both engines and they sounded good. There is a good possibility the ground cable was not doing a good job at grounding and could have caused the spark plugs to miss occasionally. I guess I will find out next weekend when I drop it in the water.
