Just got back from a week vacation and went down to the boat. Smelled fuel! Found around 1/2 gallon on the tank bunk and under motor/tranny. Must have just started. Got the tank pumped out and cleaned up today. Looks like I have to pull the motor to get the tank out.

Has anyone put in a smaller replacement poly tank on their 3270?

Thanks

I can't spot the thread at the moment, but there was a post a while back about someone pulling the tanks in a 38xx, and they found afterwards that the fuel sender and/or some hoses were leaking when the tank was full AND the boat was running in a bow-up attitude (apparently, the connections are at the aft end of the tank...I generally don't fill my tanks over 3/4 or 7/8 full after I read that). Since you just returned from a trip (I'm assuming on the boat), it sounds like it's worth checking. You'll have to search for that thread, but it's prob worth checking everything else before you go to all the trouble of ripping the tank(s) out. In the 38xx, the tanks are under the bed platform in the guest stateroom...I don't know where they are in the 32xx (sorry).

HTH,
Dave

Thanks for the insight Dave, but it is indeed the tank itself. I have my work cut out for me on this one

Hi Sean,
I replaced both of my tanks recently with 60 gallon poly tanks. Removing the old tanks was the hardest part of the job. I was able to cut the old aluminum tanks in half using a nibbler and sawsall. I did not need to remove my motors to get them out. The new poly tanks were a tight fit going in the hatches. I can get you the tank model numbers if you are interested.

A model number would be awesome. Did you worry about any sparks while cutting out the old tanks??????

if it is gasoline worry about the sparks.
we removed a diesel fuel tank with sawsall and no problems on a californian.
interested in the poly tank. do i just google poly tank or is there a link available that can be used.
I assume if a poly tank is used it can be slipped in, straightened out and than utilized.. is that how they work?

I replaced corroded saddle tanks on a prior boat with poly tanks from Moeller that were smaller but much easier to fit. Moeller tanks come in many different sizes, shapes and capacities, so it should be no problem finding tanks to shoehorn in. Good luck and I hate it for you having been there myself once upon a time.

another option is to consider a bladder inside the tank, or a sealer coating. Contact Devon Bjerkness in Bellingham.... he has a business cleaning tanks and would be a good resource for you. good luck.

If you want to keep the 100 gals of capacity without pulling the engine cut the old tank in half and remove. Repair shelf that tank sits on. Install 2 fifty gal tanks with crossover pipes at bottom and top of tank.

Go boating.

I replaced the tanks in my 1983 3270 about 10 years ago. While you may not choose the same method I used, if you look at the site below you'll get an idea what you're in for. It's not pretty.

Good luck.

I just pulled the starboard engine out of my 3270 and started to clean it up. When I get it checked out, cleaned up and repainted I will pull the tank. After that I will pull the other engine and repeat the process. With both engines out our boat will get a very intense bilge cleaning and repainting with a flameproof epoxy paint. Then all wiring and plumbing will be updated. The boat is 35 years old so it is time for a complete redo not just a tank replacement. Of course it is an advantage to have her here at home with access to a crane and forklift to make the job easier.
The pictures are after my first pass with the pressure washer and wire brushes.
