Sent you a PM ....
What rpm's are you turning at that speed ?
If your rpm's are in the low range of "Max rpm's" maybe try a 23P Laser II ...
But 62 mph is a pretty good number for your set up !
I had a trim gauge but never used it, preferred to go by seat of my pants ..
I watch rpm's and GPS, when it's trimmed to far rpm's go up and GPS go's down.
My speedo is pretty close to my GPS so most of the time I go off it.
I don't pull skiers or tubers, and do most of my boating on rivers with speeds in the 40 to 50+ mph range.
My CV is set up for going fast in a straight line and will blow out on turns.
The Laser II has the best feel / speed of all the props I tested.
" I hadn't realized documents like that were still around "
Look through this section, all kinds of cool stuff ...
