There are many different variables that are not in your post. What region do you live and run your boat, rpm range with either prop, weather, etc. With the 150hp engine you are under powered for the Sabre and therefore the top speeds are not going to be record setting. What are your expectations on this settup? I personally think you are trying to turn way to much wheel. Shrink the pitch up a bit and let that engine breath out to where it will get at or close to the rev limiter then you can fine tune it from there.BrianBrianHAWG Hunter2013 BassCat Eyra2013 Mercury 250 Pro XS Gen2 L/U
