Hello all, i just recently bought a Bayliner 3870 with Cummins 6BT 315hp motors. We bought the boat in Seward, Alaska and plan to at some point relocate the boat to Homer, Alaska.

Just curious if anyone else has one of these models with the Cummins that could give me a good base line for fuel usage. The boat on sea trail cruised at about 2200 rpms at about 23 mph.

The only other boat in Seward I know of with replacement engines is the "Wild Willy" on D dock, that boat has 2 300 hp Perkins diesels. That boat has similar performance, it goes like a bat out of hell.
My 3870 is on D dock also "ALASKA 33", 2 270 hp GM gas engines.
I should be back in Seward about 23 May.
