Yamaha 200 v6 on a 20' master angler?

[WillyC]

I have a 1993 yamaha 200 carb'd motor on the transom of my 20' seacraft. Its the SF model. Lightly loaded with just me in the boat, I can cruise at 28 mph burning about 8 gph which is 3.5 miles per gallon. Not bad for an old 2 stroke. My boat has no T-top but does have a 36 volt trolling motor on the bow and 4 batteries under the console. Original floor and the scuppers (out the transom now) are about an inch above the water line.
