Ok guess ill give this a shot. Most of you guys seem to know more than me.
Yesterday went to take the family and neighbors tubing. I have as 22' Bayliner Trophy with a Mercrusier 4.3 190 I/O. Got GAS at shell. Then launched and she started up fine as usual. Put her in reverse and backed away from the dock without letting it warm up enough or so i thought. Put her in gear to take off and she stalled out, I proceeded to start her again and she wouldnt start. Set there for 10-15 min because i thought i flooded her. Finally got it started again and it stalls. Got a short tow back to the dock. Set there and finally got her started Put the family on the dock and took her for a short test run. RAN GREAT! Come back to the dock and reloaded everybody. Stalls again. Got her started and let her idle to get to temp 175 degrees. Load everyone up and she stalls again. So much for tubing today. Packed thgings up and headed home Changed the fuel filter/ water seperator and it with gas to the top and put it back on. Will crank but not start. Checked the plugs they look fine plenty of spark pulled the air filter looked into the carb plenty of gas going in while in neutral giving it throttle but wont start. Spray some starting fluid into the carb and it wont even act like its going to start.
Kinda got stumped at this point. I also put an additive into the tank to dry out any water. I used the boat almost every weekend this summer in the cheapeake bay and no problems. Lurking through the forum it seems its electricla rather than fuel to me because even when i spray starter fluid into the carb it dont react whatso ever.
Any body got any ideas?
