I have a 34* MT with a 120 lehman turning a 21''x16'' prop*tru a 2-1 gear** I have put over 1400hrs in the last 4 years often running 12hr*days* I have cruised at 1650 rpm to 1800 rpm, my question is...* What is the best rpm for this motor for economy?* It seems the temp rises just a bit at 1800* maybe I am running to easy at 1650 rpm* Is there reallt ant difference?* How often are you guys adjusting the valves on these motors** This has been a great motor never missing a beat
