The patient is a 1993 Larson 201se with a Volvo 501b DP drive.<br /><br />History - motor over heated last year when the raw water hose elbow broke on the outdrive. Motor replaced with remanufactured engine from Vesuvio.<br /><br />These are the symptoms that existed on the old motor, and now the new motor:<br /><br />1. After warm up, 50% of the time the engine will not start shortly after shut down. Leaving the throttle wide open and waiting 20 minutes and it will restart 100% of the time. Suspect flooding, but don't see fuel flowing into the carb after shutdown.<br /><br />2. About 50% of the time, the boat will stumble and bog when pushed onto a plane (for example, pulling a water skier up). Once on a plane and RPM builds up, it runs smooth.<br /><br />I've swapped the raw water fuel filter.<br /><br />I do not believe the carb has ever been rebuilt.<br /><br />Questions:<br /><br />1. Am I on the right track with the diagnosis?<br />2. I am a reasonable mechanic (work on old Audi's and my Miata - I've done jobs like timing belt replacements, etc). I have not ever rebuilt a carb - how bad is it to rebuild a holley 4 barrel marine carb? Is it something a shade tree mechanic can do, or should I send it out?<br /><br />Thanks!<br /><br />Jim
