I have twin optimax 135's on my boat. When underway at crusing speed (3600 - 3800 RMP) my port engine, on occasion, looses RPM (goes to about 3000 RMP). The maintenance was just done on the engines, but the problem continues. Any ideas???

Ahoy, Sea_Trek.<br /><br />Sounds like you have an intermittent failure of an injector or ignition on one cylinder.<br /><br />Check for wires that may be arcing to the block at times.<br /><br />Good luck. :)
