The best cruising RPM is determined basically by the "sound" of the engine.<br /><br />However. if your wide open throttle RPM is not within the makers recommended range, you may be lugging the engine-not good.<br /><br />Post your wide open throttle rpm, we'll go from there.
I am getting 5500-5700 wot. I just went down in pitch from a 19 to a 17 big difference in throttle responce. The motor sounds the best around 4200 and up. Just looking for some opinions.<br /><br /> THANKS
OMC used to advise that the best performance/efficiency was WOT less 10-15%. I agree with DJ that most motors have a "sweet spot" that you can identify by sound. I run a pair of 1987 110 hp and they are happy at around 4500 rpm. That will change some based on load.
