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.

I did replace the filter. I started it with starter fluid a couple time and it would run for a while, but if I came down to idle and it died it wouldn't restart. Someone told me to dump Sea-Foam in it and see if that works. Guess I will try it but starting to think it is a carb problem. Jets clogged or something.

Or a fuel pump going bad. Disconnect the fuel line at the carb and crank the motor over if a manual fuel pump. Or energized it if electric. See what kind of fuel flow you have to the carb. After changing fuel, filters and adding heet, it should atleast start and maybe run a little rough. Im thinking a fuel pump is going.

If there seems to be good fuel supply going to the carb, I would remove carb and shake out, dump out anything in it, the bowls may be full of water and it is not being displaced by fresh fuel. Most any auto mechanic that has the space and inclanation can work on your 350, don't need a special airboat guy to fix a fuel problem. BudWasilla

I have plenty of output from the fuel pump. I used the fuel pump to help drain the system after I couldn't get anymore with siphon hose.

I have it running right now. Put Sea Foam in the Fuel/ Water filter, a quart of Sea Foam in one of the 25 gal tanks and spraying Sea Foam directly into the carb. Have throttle held at about 200 RPM's. Been runing like this for about 20 mins, with a few high RPM's in between. Then I will see what happens..

We shall see. After an hour or so of running, I shut it down and had a hard time getting it to start again. Ran to town, came back and it started without any starter fluid. So I will try tomorrow after it has sat overnight and see what happens.
