Running at less than WOT

I understand it's important to have your motor propped so that it reaches the correct rpm at WOT. I have a 60 hp 1994 Mariner on a 17 foot Monark aluminum boat, runs 5500 rpm at WOT, which appears to be right on target. Is it ok to reduce the throttle while cruising, back to about 3500-4000 rpm to save gas and wear/tear on motor, or would this be harder on the motor? The boat runs just about as fast at this rpm (or fast enough, anyway) and probably eats a lot less gas, but I don't want to do anything to hurt the motor. Thanks.
