Here's the history. We've owned this boat for 5 years without the current problem. It's a 97 SeaRay Dancer, powered by a stout 7.4/300HP, TBI,Electronic Ignition engine. This season our boat will start and Die after maybe 2/3 seconds.This happens after short duration stops such as lunch. First start of the day, no problem. Let it cool for a few hours and there is no problem. I've rebuilt the Distributor, replaced the IAC, Temp Sender for the ECM changed out, installed a new Ign.Cap, Rotor and Coil. The Fuel Filter is new. I've added StarTron and an appropriate amount of Marvel Mystery oil. The gas is from last Sept./07 10% Ethanol :smt101 so I added a few gallons of Aviation Gas to freshen it up.
When the engine refuses to start there is Ejection from the Injectors for the 2/3 seconds it runs and then nothing. I'm inclined to think it's Vapor Lock due to the old fuel. When started she runs very strong.
I'm going to put a 160 Degree Therm. in and try to open the Hatch when stopped to see if it helps. BTW, it's a closed cooling system. I may add Water Wetter also. All opinions are appreciated. Thanks! Al W.:huh:
