Re: Fiberglass fuel tank replacement in a Bertram
I have seen a very large (1000-1200 gallon) fiberglass tank installed in a large Bertram sportfish. If memory serves the tank was glassed in as part of the build process in the bare hull. If your tank needs to be replaced, it may be necessary to cut out. (assuming Bertram used the same method on your boat)
It may benefit you to contact Bertram directly to verify how the tank was installed. If it has to be cut out, it may only be necessary to cut the top out of the old tank. If you can get to it, the old tank body would be perfect place to put in a new aftermarket tank.
Note- Be careful cutting fuel tanks. Fiberglass can carry a static charge. It may be a good idea to fill the tank with water to displace potentially explosive fumes while doing the cutting. And make sure any fuel lines, filter housings or gas that has spilled in to the hull are removed before cutting. Be safe, dont guess. If you are not confident you can do it safely, hire a professional.
