You should be turning between 5500 and 6000 wide open.
do you know what your props pitch is?

redroaster 07-15-2014 12:36 PM

Pitch is 17
Running 45 mph and 5500 rpm wide open
Looking at raising engines up as well
Enertia or thunderbolt prop or powetech 4 blade also
Definitely changing hubs and props

Is that your gps speed or speedometer? I ask because one of those numbers isnt right. When I calculate your propeller slip it comes out negative which isnt possible

42 MPH on GPS and 5400 RPM's
 
42 mph on GPs or 36knots which matched up with speedometer and 5400 RPMs WOT
ken said its around 3 to 5 % slip ??? not sure i am saying this right?

cruising was 3900 RPM's and 30 mph or 26 knots on GPS

redroaster 07-22-2014 12:52 PM

prop numbers were:
17 TL
15 1/2

3-5% slip is really good, so raising your motors or trimming up more while you are running is probably your only option. A four blade will give you more hole shot, but reduce your top speed

thanks for info!
