I recently bought a used 1989 Grady White 19 Tournament, but it has a gas leak. Can the tank be taken out without having to cut the deck? The tank is 64" long and the opening is 62 1/2" - I trimmed the flanges lid and it seems to be close to 64" now, but doesn't want to come out. Do you have to trim part of the deck or is there a way to get it out?
