Make sure it is rated for gasoline. I got myself a gas buddy from amazon for this purpose. IIRC, they come in two flavors. Get yourself the high-speed version.

Gas rated electric marine pump ($$) or a auto store fuel pump (slow and gotta watch it so it doesn't overfill) properly wired with a switch for the purpose :evil:

Get an inline 12v fuel pump pop it in line and let it do all the work for you then you have a fuel pump to prime the system later.

I mean gas tapper.

Use a hard plastic tube to reach down to bottom of tank.

You'll be able to remove almost everything from the tank, including all the accumulated water, or the waterline antifreeze your helpful kid inadvertently added to the gas tank instead of to the water tank. Or so i'm told......

I just removed 80 gallons of water contaminated fuel out of my port saddle and stern tanks. I used the Carter Electric Rotary Vane fuel pump that had been installed for the port engine. After consulting with Beacon Bob, I had to add fuel to the tanks once the pump couldn't pick up any additional fuel to counteract the slight difference in the pickup tubes since they don't go all the way to the bottom. Then I extracted the new fuel to ensure I had most all of the contamination out.

Shockingly, the previous owner left the fuel fill caps off the port stern tank after losing it and I extracted over 14 gallons of water from the tank before I started getting fuel mixed with water. This saved me from having to disassemble my tanks, which I really did not want to do with all of the other projects that needed to be completed before the boat is ready to use this year.

Once done, I replaced the fuel/water separator filters.

Use of the Carter 12V electric pumps, which are rated for gasoline, is the safest way to remove fuel. If the tank ports are already exposed, just slide a hose down one of them to the bottom, attach to the pump, and pump away!

For those wondering, I was able to give the fuel to a local guy who uses old fuel to run his military play toys. He lets the water settle out and then extracts it for environmentally safe disposal. Recycling at its finest.

Well I am dealing with bad fuel again this time however both my 80 gallon tanks are full. They where about 25 percent full last year at the end of the season, I only ran the boat a few times last season with no issues. I did put in stabilizer at the end of the season and topped up both tanks prior to launch this year. I have been practicing docking for a couple hours a day last few days and today took the boat out in the channel for a bit. Ran it low speed for about 10 minutes then went to increase speed and the one engine started back firing and then died and made it back in on the one engine. I spun off both fuel filter dumped them in a clear jar and they had alot of particles in the fuel. Started motors back up they ran good a few minutes then same thing. Spun the filters junk in there again. I was through this a few years back but had very little fuel in the tanks. This is alot of gas to get out.

I would try pumping out some fuel from the bottom of the tank

I will give that a try.

One motor seems worse off then the other, and that is the one with the older tank. I guess in reality thou there is some gas in each take that could be 3 years old. I guess I should have drained what was in there to start with.

I decided to try and run both motors off the same tank. The tank of the motor that is running good. To my suprise both motors are running great. Both are even idling low. I havnt left yet so will see when i go for a run if the problem was the old tank. My slipvmate has offered to come along so hopfully will do this soon

No luck. Lost starboard motor when leaving the dock. Wouldnt stay running.

Port side motor running good.

Any suggestion. Think to tear apart the carb and clean it.

Still trash in the carb or maybe a pump issues . look for lines sucking air
