First weekend out engine would lose power as if fuel pump/filter was bad. Engine would start and idle and move at low RPMs but would bog down and die at high RMPs. After replacing both the fuel pump and filter the following weekend's run was worse. Engine stalled and would not restart. Stater would not turn and the only thing making noise was the solenoid. I have two batteries working in parallel and both checked out. Even tried hooking up to newer fully charged batteries to attempt to start with no result. After getting the boat on the trailer and returning home I was able to get the engine to turn and finally start with some effort. I replaced the solenoid with the hope that it would fix the problem and found once I did the boat started and ran while hooked to water hose and running in neutral without any problem. This brings us to this last weekend where the same problem occurred after a short run under power, the engine faltered, died and would not restart. No movement from starter and not sound from solenoid, I have yet to get it started again, the noise that was coming from the solenoid the first time is gone this time. There is only a light click followed by nothing. After it died the final time the only other change I noticed with the cowling was a light swizzling sound coming from the area of the starter and solenoid. Also main cable were quite hot to the touch. Batteries still show good. I would appreciate any help with this matter and thanks for taking the time read my lengthy post.
