Water in fuel tank.

[mawshj]

with boat on trailer I connected a hose to the output of squeeze ball and went to 5 gal buckets on ground . water should (siphon) come out first then switch to another bucket (s) for remaining gas. throw away first bucket the rest should be ok for water separator to collect.

The water will hide in the lowest corner of the tank
ALSO if there was any ethanol in the gas the water will have pulled it out of the gas leaving you with very low octane.... I suggest removing everything from the tank and having a bonfire.

What i did with mine i disconnected the fuel line going in the engine at the fuel pump, i have a 2006 mercury and placed it into a 5 gal bucket. Then i disconnected the fuel vent line and with a compressor i blew air in to it and the fuel started flowing into the bucket.

VERY risky... as little as 2-3 psi could cause MAJOR damage including a ruptured tank and or structural damage to the boat.

Very true!
The tanks are pressure tested at the factory at only 3psi.

Here is the filter/screen and location off of one of my saddle tanks.



And the anti-siphon valve balls at the same location.

Yep and when the pressure test them they are put in a fixture that keeps them from ballooning.... They should never be pressurized outside that test fixture.

I drained my tank as much as possible then went in thur the sending unit hole with rags and dryed it out dry, water gas all gone!! get rid of the antisiphon ball now before you have problems eith that cause you will!
used the gas after letting it sit in my truck pouring the gas off the top of water.
good luck

My 1989 V 20 would get water into tank from the tank air vent mounted on hull.Simple to fix was placing a stainless air scup crowl over the vent to block the water n spray from going up into vent then into the tank..
