Hello,

Could anyone tell me the size of the fuel tank for my 1987 Sea Swirl Sierra II OMC? I have not been able to find this online. Just trying to figure out the correct amount of gas stabilizer.

Thanks for any help

A lot of boats will have a hatch for the fuel gauge sender. Sometimes you can see the gal marking on the tank. You can also guess, based upon the size of the boat and motor.
