......what is the fuel burn rate on your boat?

I have a Glastron GS209 powered by a single 4.3L 190 HP engine. I
tracked the fuel burn for several months and it generally calculated
out each time to be between 2.5 GPH and 3 GPH.

How about yours?

When the fuel guage stops bouncing I get worried. Until then I just fill
the tank. I used to get 1.75-2 mpg average for a day. Probably better now
that I have switch to an EFI 350 vs. a carbed 351W. That is some 35-40 mph
running the river and some 25 mile per hour running. I troll with a Yamaha
T-8 and that gets about 1 sip a mile.
