Hi, I have a 1997 V6 175hp EFI mercury and its broken down the last 3 out of 4 outings. I've taken it to a Marine mechanic the first time it broke down, he ran a few checks including fuel pressure test and tested it for ethanol and all came up okay.
Boat will start at home, start at the ramp, start in the water and run okay until you reach your 1st destination which can be anywhere from 5 min run from the ramp to 1 hour run. Once you try and start it after you have stop, it will crank but wont fire up. It doesn't overheat at any stage, you can drive for hours around on the first intial fire up, its just starting it up after that. Last time out I removed all the spark plugs and they were fueled up. Anyone had a similar problem or have any idea's?? Could it be possibly a sensor ECT, IAT, Crank angle sensor etc ??
I have tried searching this forum for a repair manual but cant seem to find one!!! Any info would be greatly appreciated.
Regards Charlie...
