Glad I did not offend. I'm thinking along the same lines. A healthy motor should pull a 48-52 MM prop with 3" of pitch even at 4000' elevation. I try to build as light as I can and keep the balance point 1/2"behind sponson transoms. Still haven't heard a word from anyone who has even tried a 1650.
Glen i have to say i was a little hesitant to say but on my old Whiplash(the yellow one in my gallery) i tried all the rigger props i had in my box......1657 1460(reduced to 57mm) 1655, 1455/3 and 1455/2 at my home lake i could have pulled all these props i got my whiplash up to 66mph(on gps) with the 1657 but the pipe had to be a little longer to pull it off the shore the top speed is great but the launching is a pain what i found was that the 1455/3 and 2 were the best props. with the high lift props the strut has to be very high something like 1/2" to the bottom and some negative angle of the strut from the bottom of the boat or else the nose will submerge. in 2008 i took the same boat to the winternats in Florida and learned that those props didn't work. i needed a smaller wheel like a 646/3. i can't speak on the 1650 but i do know for sure that the 1455 is a great prop you just need to reduce the diameter and take some cup out, i'm going to test it on my new whip and let you know what i find
im running a 1455 3 blade on 60 % on my mto
Good to hear from the Mile High Club! The two P.T. SS 45's at our lake were running best with the Prather S-230's pipe around 11" at the the end of last summer. My new boat is one of Phil's round nose's and setup will likely be diferrent. Gonna follow Phil's instructions on strut depth- 1 1/8" bottom of hull to bottom of strut. Boat is still at the painters as we speak
The best prop is a stock 1455/3 with rounded tips
