Hello, I have recently purchased a 2016 Blue Wave 19stl W/Suzuki 140DF and I was seeing if anyone on here owns a similar model that I can pic their brain. I have a 4 blade 20 degree prop and it just doesn't seem to be running the way I thought it would and have read other places. My cruising speed on it is about 30 MPH at 5,000 RPM with just me and another person and gear. Also it doesn't seem the hole shot is that strong for having a 4-blade on it. I feel the boat should be running closer to 40 at least near 35, what is the safe cruising RPM I should run and what should I except for Top End speed on it? Also I am a first time boat owner so take it easy on me.
