I have not myself removed the
fuel tank from my 1975 Ontario 32, but it has been replaced in the past. About twenty years ago, the original owner had the
Yanmar 2QM20 pulled out and rebuilt, and I expect that the tank was replaced at that time. With the
engine out, they would have been able to pull the tank forward over the cockpit drain thru-hulls and then out through the
engine space. Can you slide the tank forward enough to maneuver it out into the cockpit locker?
Currently my
boat is equipped with a Moeller black plastic tank, capacity somewhere between 76 and 80 litres (about twenty US gallons). I believe that this tank is small enough that I would be able to slide it sideways and then rotate it into the cockpit locker, if the need arises.
By the way, there is an active Facebook group for Ontario Yacht owners. It is always a good place to ask for help and
advice.
