Craig, the 29 did not work with my 1.62 gear, it would only turn 5400rpm's so I traded it for a Roy Roach worked 28 to a 27 trophy plus with the Allison cut and some tip cup and so far it is my best prop. Still it only turns 5900rpm @ 93.3mph with 3 people in the boat. So I think a 26 Hydromotive will get me closer to the rpm range, will need the blow-out ring and the pvs holes though.
