Hey Guys,
New to Nitroowners. I just bought a 2019 Z18 with a 150 Pro XS four-stroke. This engine came standard with a Fury 23P 3 blade prop with all 3 PVS holes fully plugged. I also have a mechanical 6” slide master jack plate. Running approx 2-1/2” below pad. Boat runs very smooth, pops up on plane. however, here’s the problem...
Running some tests during initial break in period (so not running WOT for more very long), it appears to getting around 5800 RPM, but maxing out top speed around 54 MPH. Seeing what others are getting out of there 150’s and Z18’s seems like I should be getting closer to 65 MPH?
Load has been approx 1/2 tank of gas, loaded with tackle and just myself and a passenger.
Do you think my prop pitch should be 24P instead of 23P, engine height adjusted? Jumping on plane, Cavitation and/or slip don’t seem to be any problems. I get some porpoising when coming down to low speed planing around 3500 rpm, but nothing adjusting trim didn’t smooth out as normal.
Thoughts? Thank you ahead if time!
