My airboat has a fuel issue. I had some water in the fuel but drains the system and put clean fuel along with Heet. Ran the boat here at the house and didn't seem to have any problems. Got to the landing tonight and it didn't want to start. Used starter fluid and got it to start and warmed it up before putting it in the water.Llaunched it, cranked it up and moved it out of launch area so I could go park the truck. Go to take off the it wouldn't start. So I just brought it back home..now I need someone that knows what they are doing to look at it. So who do you guys use. Power plant is a Chevy 350 w/ Holley Carb.
