My R25 with my 200 SHO will plane but will not keep the bow out of the water at 3500 RPM so I cruise at 4000 which gives me about 20mph and I believe around 1.9 mpg.

I am much happier at 5000 RPM and I get closer to 30 mph but I have not computed that FF yet and can only imagine how much worse it gets!

I'm running a 14.25 X 17p 3 blade prop and I am happy with it so far (3rd prop) as it gets a good hole shot and gives me max rpm of around 5950 which is what I was looking for.

I don't want this thread to get into a 3 page prop discussion... there are plenty of those... I just would like to know what RPM you generally set for long range cruise and the speed you get. If you have fuel milage.... even better!
