I have a 1986 Sea Ray Sundancer 25. Just discovered the gas tank has a leak (small - but likely others as well) in the bottom (70 gal). Suggestions for repaor or other options without removing the engine to get at the tank (to replace).
 
There's no way to repair (most likely replacement will be needed, though) without getting the tank out. And that usually means removing the engine. There's no magical solution here. Removing the engine is a pretty straight forward job for someone with experience and doesn't take all that long.

Don't mess around with this. It probably goes without saying, but DO NOT use the boat again until this is fixed.

Much appreciated. Sound advice. Was hoping didn't have to remove the engine as I just replaced it....now have to remove once again. Ugh!!
 
There's a small possibility you could pull the tank aft and then angle it up. Hard to say without being there to measure or at least seeing the bilge. Depends on what you can remove directly above the tank, too. Measure the length of the tank - that'll give you an idea.

But if you did it once, it'll take you half the time this go around! :)
 
Indeed. Lol.
I'll check your alternative suggestion. Leaning to engine recoval though.
Thanks
 
Check under your aft cabin mattress. I read a post where somebody was able to get their tank out that way but not sure what model it was. might be able to get away with taking the plywood off the aft cabin and removing it that way
 
Ok ....definitely investigating that option.

Have you checked this out yet? My boat must have had a tank problem and they stuck a 30 gal beside the motor. Cruising range sucks.

Going with the engine removal.
