Thanks in advance guys, My 1st post. I recently took a trip from mathews county Va. Down the bay through Norfolk. Went down the intacoastal water way to the outerbanks, stopped at CoinJock fro lunch and take on some fuel, while refueling one engine shut down on its own,when finished fueling it fired right up, left the dock and then starboard eng shut down 30 secs later the port engine also shut down, Didn't appear to overheat, checked water from pee hole on both engines, water felt to be at normal temp. Pumped both bulbs about 50 time apiece , (Which is abnormal,) usually only have to pump them about 7 to 8 times apiece to get them hard, Anyhow they fired right up no more problem going down there, running offshore one day,no more problems until On the way back home and about halfway back up the ditch while waiting for a bridge to open it done the same thing. Any thoughts on this from anyone? I'll give a little more detail, I have a 2003, 330 express, with twin 225 yamahas 4S about 900 hrs on motors, I had it for appr. 2yrs. Haven,t had this problem before, Was traveling with three other boats that were quite a bit slower than me, I was bringing up the rear, Unable to go much faster than 7 to 10 mphs while navigating the intrcoastal due to traffic, I was wondering if my problem was caused by not being able to let the boat get on plane and run, It was around 90degrees both days, One of the guys on the other boat thought maybe motors had got to hot and vaporlocked the engines, Or was Ethanol the problem,( Vaporized while the engines were idling ) causing the vapor lock. Has anyone here had the same thing happen to them and if so what was the problem, By the way boat hasn't miss a beat since then. Thanks again!! raise
