I tried MILES OFFSHORE (Craig's) prop when I first put my motor in and could only turn 4200 rpm and the four barrel did not open all the way, the 17 x 16 gave me the 4600 that I was doing. I had a new tach and Meercusier make a digital for aboy $75 that I have to compare RPM's which gives a accurate reading, it wraps around one spark plug wire and ground. I have had trouble in the past with a Tach reading the wrong RPM's.
