I have a Mariner 150 V6 2 stroke. Normal cruising at say 3500 to 4000rpm gives about 1ltr per mile

well wear on the new craft.
I used to run a Yam 150 ox66, with the fuel management clock (in this case better not to know!)
75l/hour at full chat.
35/40l /hour cruising at 3800rpm

They sound great though when underway and easy to live with from a maintenance perspective.

Results are in!!

I got the Navman fuel 3100 working (thanks youtube) and im able to see what she is burning.

At full throttle im burning 70lt/hr doing 44kts

On the cruise (3800rpm) im doing 25kts and burning 30lt/hr

At 3200rpm im doing 20kts and burning 27lt/hr....It looks like 25kts and 3800rpm is my happy speed!

I must say its nice to have the fuel comp working, I have burnt over 350lts in the last 2weeks, This summer rocks!!
