I bought a 20ft. Campbell recently. It has an LS-6 .30 over. 830 holley, single plain manifold and roller rockers. Has a Casale 500C with 22% od gears, spinning a 13/11 3 blade prop.
Had it out today and ran it for about an hour, from Windsor launch ramp down to Copper Canyon, by the time I had got back by Crazy Horse, I had used up 1/2 tank of fuel. My tanks are 30 gal each.
I was only running it at about 2600 rpm for most of the time.
Any advise as to changes needed to make this alittle more fuel friendly?
We will be using the boat for basic cruising around the lake.
