Bill,

This is a fairly light boat, 4000 rpm might not be the most fuel efficient
cruising speed. The boat will probably plane at 3000 rpm. I had a Volvo 6
cyl. a few years back, and the best mpg was at 3600 rpm.

Your buddy can buy a Floscan fuel meter for about $300, or he might be able
to borrow one at his local marina mechanic. This will give his boat's best
mpg and gph.

Hi All,

A fishing buddy has a 17.5' Crestliner walk through aluminum boat with a
Volvo 3.0 GS (4 cylinder 120 hp) I/O.

It goes 30 mph @ 4000 rpm and top speed is 39 mph.

What should his fuel consumption be for this boat while cruising @ 30 mph?

He is wondering if his boat is consuming more fuel than it should be.

Thanks for any help.
