Hi, newbie here, I have a ,91 20hp Johnson electric start on a 11' Boston Whaler, and am curious as to what the fuel burn is on this engine.
The reason I ask is first because it has a new (installed by previous owner) 6 gal. tank in the stern, which seems to a lot of weight & fuel to be carrying around, secondly I use the boat as a dinghy for my larger boat, so I thought I might get by with a 3 gal. tank. While I'm asking questions, what size battery do this motor need for starting? It currently has a new group 24....which seem overkill & heavy!
Thanks muchly for any input.
