I have a question on comparing two props one is a 70x72 warnke and the other is a 68X74 warnke. How much difference is there in hp requirements and performance of the two props? The 70x72 is no longer usable, the 68x74 is for sale, but don,t know how close they would be. The 70x72 was perfect on my RV 4. 0-320 with 150 hp before its demise.
