On my 3700, I took an inch off my props to get up to 2700 rpm (was barely getting the spec'd 2600). I noticed the engines seemed quieter at cruise. I lost a 1/2 knot at 2200, so I just bumped them up to 2250 to regain the speed (22 knots). Fuel consumption actually is better now, and less soot in the exhaust. You'll be glad you made this change.
