Hi , im new to boating , purchased my mustang waverider in sept, and new to the forum aswell, always wanted a speed boat and finally pursuaded the wife and 2 kids that it would be a great investment!
we took her out on the welsh coast in old coway, ross on sea and had a good couple of hrs, infact it was that good we did the same the next day, this time as we set off , just warming the engine up, she was running a treat,then suddenly the engine revs started to drop offuntil the engine stalled sounded like fuel starvation, tank was full and prime bulb was 'hard', me being the novice , i tried to start her but failed , wasn't sure if i was flooding the eng with my overzelous use of the auto choke on the key, any way , much to my wife and kids embarressment we were towed in by a very helpfull fishing boat, once along side we turned the key and she fire up! after about half an hr same thing again, i noticed the fuek connector on steel tk was badly corroded up and cracked open tk lid , this had some pressure build up, engine ran ok for a while then died off again,so we called it a day. once home i flushed engine thro so it starts ok first time and seemed ok when revved, stripped the 3 carbs and found middle carb gummed up and looked like the high speed jet at base of float was blocked , so cleaned out and put her in for a service just incase, he said the top carb was running a bit rich but overall the engine is in good order, as i intend to use the boat in winter i was wondering if anyone else has experienced such problems or am i over reacting as i have yet to give her another test run in open water. also i cleaned the fuel tk and put a new fuel connector on outlet and i found the 2 small vent pins on the tk were seized, so freed them off aswell, could this have been the problem ie tk not venting properly , i have stripped the fuel pump and diaphragm ok, my only other thought is the pump itself as it is electric and not run off the crank, possible electric fault ? a new fuel filter has been fitted also.
