ok... just to add to this post... Different boat same prop!
25 OL w/454mag (just me, as bgmac didn't want to come!) 3/4 fuel 85 degrees. cool breeze~

odd #'s but did have GPS
walked up at 2500 and jumped out of water when at 3k! liked that!
3500 at 38mph
4000 at 46mph (didnt like the loss I took from 23p m+ from 48-50 depending on load/water)
4500 at 56 mph (6% slip.. not bad)
5150 hitting rev at 61.8.

odd part: gained 10mph from 3500 to 4500 and only 6 to 5100obviously slip was better at 4500 as i was able to trim up. Also tried to play with at cruise speed (4k) and only able to pull 46mph!

Ruins my plan at going to a 22B1.. Loss of pitch not going to accomplish my goal of good cruise and still rev to 5000.

probably need to test your 24p b1.. then lab to get rpms back

If you're talking to me, Rev4 21 spun 5600 rpm at 69 GPS with the 1.5 and -2 sportmaster and the same with the standard drive. I also only pulled 53-5400 with a B1 22p at 66 gps and 70.4 at 5600 with a 21p M+

thanks for reply... I am stuck... 21p rev 4 couldnt get top end or cruise like I wanted.. thought a 4 blade would have less slip.. but I have narrowed my choices to 23 labbed to up pitch and get extra 200 rpms or lab a 24p b1 to get extra 300 and some extra bow lift...?
