    Ok, finally installed the Tiny Tach. Actually had to send the 1st one back because it didn't work. Took the boat out yesterday and got some numbers. WOT rpm's were 5820 and ran aprox 25mph with a full load on the boat(2 people, fishing gear, gas and trolling motor. Im happy with the speed but would like alittle more bow lift, boat has a wet ride and that would help. The prop I have now is a 13pitch but is really beat up. Recomendations on what prop to get? 3 or 4 blade?

    Try a 3 blade 12 pitch.

    Reasoning for your recommendation? What is the advantage of the smaller pitch?
