Default Re: Gas Tank Crud...Anybody?

Ethanol in the fuel. Been seeing it in lots of boats. That is what it tends to look like. How long ago did you put that 50 gallons in the boat? The longer it sits the worse it seems to get.

nyway, my best guess is that the ethanol (with 1,800 miles of agitation to aid the process) disolved some or all of the varnish that had accumulated in the tank over the 19 years since I bought the boat.
I think the problem is identified. I put that gas in last November and did not burn it out till March.

The previous owner always used non-ethanol gas...but never ran the boat off shore. So I guess all my bouncing around has stirred up the dissolved varnish. Like gofast said maybe two or three more filter changes will do the trick.

Engine runs strong and then like some one turns on a light switch and bam...

So an extra filter on boat at all times and change at the first sign of trouble or check every 10 hours.
