Sorry Denny, I misquoted the price. The Power Tech OSF 4 15.25 x 15 is $499 at Prop Gods. I like the idea of exchanging props. In the efficiency category is there a breaking point at which say a 15.25 x 15 turns 5300 revs., but a 15.25 x 16 turns 5500 revs, is the 16 "less efficient" because you're burning more fuel?
If I understand my Seafari, the Viper is a bow lifting prop and seems to take a lot of energy to get on plane, and falls off plane at almost 3000 revs..
What are the chances of number of splines being the same as my 1999 Johnson 175? Maybe for my next trip I will borrow the three blade SS from the MA, and see how that feels, as a comparison. What do you think?
Michael.
