Well, it turns out a new o-ring in the fuel fill was not the solution I thought it was a couple years ago. The fitting itself wasn't even tightening enough to get the o-ring to do any sealing, so I had water in the fuel again. I've been battling it for a few weeks now (since we didn't get the boat out until late June anyway! ) - and I hope to have finally solved the problem once and for all.
I've been trying to let the filters do their job, and they have, but there was so much water in the tank, they'd simply get overwhelmed and fill up and the engine would shut down. So, I'd drain the filters, popping the inline off too and draining it, drain the Racor, drain the carb and start all over again..each iteration of this over the last couple weeks has ranged from 45 minutes of run time to 90 minutes of run time.
So, today, I went over after work, and pumped the remaining 12 gallons of fuel/water mixture out of the boat, and figured I should pull the tank and make sure it is clean. A couple weeks ago I replaced the fuel fill to a newer style with integrated vent...one less hole in the boat, and a shorter hose run to boot, since the old vent went to the transom.
So, I had about 12 gallons of uncontaminated ethanol free fuel left, so I put it in the tank and fired her up. Started right up and ran great...of course it did every other time too. I'll do one more draining of the Racor, and I replaced the inline filter and drained the mech. fuel pump bowl too..it was mostly water and probably the real reason the engine was quitting.
Once the tank was empty, the removal of the tank simply involves unscrewing the hold down clamps and getting hoses off. I drug a cotton t-shirt around inside the tank to clean it and make sure there was no water leftover. I was able to pump all but just a few ounces of fuel out thru the gauge sender hole.
Here are some pics! Oh, the new fuel fill is totally plastic, so does not require a ground wire either!
Now, If I can get past these hurtles, I could maybe get on to things like the windows.
Happy Summer everybody!!
