Calling Throtleup.
#1
Julie it's been a while since you guys did the work on my prop over the winter. Unfortunately the weather has not been the greatest for testing until last weekend.
Just a refresher:
97 26 Powerquest Legend with a stock 454 mag EFI bravo drive and stock 23p Mirage prop was running at 4800 RPM
with a top speed of 57-58 GPS
After the work.
5000 RPM and just shy of 60mph GPS
One thing I've noted is I now need to slow on the throttles otherwise the prop will blow out a bit, Never seems to loose bit entirely.
I'm not sure but it seems like I have a lot more slippage than before.
Whats your thoughts??

I have a Powerquest 290AE v-hull with twin MX 6.2 MPIs. I currently have 3-blade Mirage+ 24Ps. WOT at ~5000rpms and fully trimmed.
Top speed varies with air temp/himid b/n 68-70mph on gps.
Can a different prop improve top end? Got extremely fast hole shot now hitting plane in 2-3 seconds. Any other data points you need?
BTW, your message box is full.
