Moomba Outback water/fuel issues.......

I seem to be having some problems with water getting in my fuel on my 01 Outback. I think it all started when the small glass inline filter got loose and sucked some water up and caused the boat to die. I thought it felt a little loose. After cleaning it out it took quite awhile to get running. We ran the boat around the lake everything was ok. That night I put in a bottle of HEET and filled the tank..........just incase.

We get to the lake the following weekend and the boat starts up and just dies. Then will not run at all. I take the boat home and put it on the fake a lake and get the boat running by pouring fresh gas in the carb. Another Sunday down the drain

Has anyone had any fuel/water issues? I am wondering if it is getting into the tank through the vents in the gas cap????? What is the easiest way to drain the tank? Also it is completely full, do you think if I siphon with a hose at the bottom of the tank that it will get the water first as water is heavier than fuel?

Does anyone here use an aftermarket fuel/water separator, if so where can I get one???


Thanks!

On my 2000 Outback there is a fuel/water separator already installed on the boat. It is on the right side of the engine towards the front. I change it out about once a year. It is similar in size to an oil filter. Perhaps yours is full of water; just a thought.

Water is heavier that gas. The best thing to do is drain the tank completly. jack the bow way up and syphon the gas out. Remove the check valve from the tank first.follow your fuel line back to the tank. thats where the check valve is. take it off and replace with just a standerd nipple.To make the syphon process easier I use and outboard motor primer bulb to get it started then remove once gas starts flowing. once the tank is empty put a couple of quarts of denatured alcohol in the tank. syphon that out. then fill your tank with gas. if your gonna use the old gas make sure you don't put the last half gallon or so from whatever container the gas is in. water and dirt is always at the bottom. Hope this helps.

Thanks for the input. I guess I'll start the siphoning and see how much h20 is in there.
