Jody...I can assure you that I motored appreciably aster at 3000 RPM's than at 2500...and at considerably higher cost in fuel. The tradeoff is an individual choice...and motoring on the ICW for 8 hours rather than 10 hours was often a good trade off for me. Doesn't matter much in and out of harbors buton long motoring days...that extra 1/2-1 knot can be quite important.
