'93 2700 SCR - Gas Tank Leak - Maxum Boat Owners Club

jimdandy · 09-12-2010, 03:52 AM

I've owned this boat for almost 18 years. I don't use it much. Just complete refurbishing the engines and out drives.

Now it looks like I have a gas leak. I can see it coming out the weep tube in to the bilge. I know I will have to remove the tank, but what is the easiest way to do it. Bayliner says remove the engines and take it out through the engine room. That is not doable as it will not fit through the hatch openings.

Any help out there?

Thanks, Jimdandy

Hi jd..welcome to the zoo...from my last experience, they cut the flooring out of the batcave and out thru the salon....the new tank is replaced but be sure there are no burs or screws sticking out...then clean out the bilge and replace with a new tank.....
take pic's...be fun to watch the proceedings...

Are you guys sure it a leaking tank? I thought I had a leak in the tank but it turned out to just be a loose sending unit gasket that sits on top of the tank. Just tightened it down and my problem was solved. cheepest boat fix I ever had!

Good luck

I did it! Let's say the tank is 98% out.
The best way is by using water hydraulics. Plug all the "weep" holes into the bilge,
close the drain plug on the stern. Put a brick on the flap lever of the bilge pump so it won't operate.
You must loosen the tank from the "coffin" hole first before using water to lift it.
Make sure you have drained all the gas out of the tank. Then run water in the space
that the tank occupies. Soon she pops up like a cork! You'll know if you have gas in the
tank right away because the tank will lean to that end. It would have worked better if I
had leveled the boat on the trailer. The hardest thing is to turn the tank to walk it into the
salon. Some cutting will have to be done on the port side of the rear bulkhead, but very small.

Next chapter next week.
