I have a 21 gallon metal dieselfuel tank which has been sitting empty for a very long time over two years when I bought the boat.
I have mounted a outboardmotor on the boat. The orginal engine is long gone and I have no intention of repowering.
However I am thinking of using the existing fuel tank for the outboard no sense wasting the space. However my inclination is to get a new tank more like 12 gallon (plastic) and adapt it to the existing space.
The tank for the outboard is a normal 5 gallon portable. Just thought it would be simple to mount below deck in the spot where the existing tank was for the inboard.
A search of previous post shows a lot more involved. I am guessing the engine compartment had a blower system of some sort and a venting system for the gas tank.
Maybe it would be a safer bet using the area for waterstorage.
