Default Re: Propeller pitch for 1984 23 Open Fish?

OK, sorry about the long delay in responding. Kids, summer camp, etc. Here are my conclusions after comparing the 17 pitch Mirage Plus, and the old original SS 17 pitch on the 250 4 stroke Yami: the Mirage Plus stinks on my 1984 23 cc. It drives the boat into the water, not matter how I tilt the engine. The Mirage is fine in flat water (although it still rides low, on all 3 chines). On the plus side it gives me the same top end speed of 40 mph. However, in heavy seas it simply plows into the waves, with no lift, poor stability, and soaks everyone, constantly. I am going back to the 15-20 year old SS 17 pitch prop. That old prop gives great lift, and eats up heavy seas, riding high. Frankly, I don't know what I was thinking going to the Mirage. I ride on all 3 chines, or at least 2, at all times with the Mirage. Perhaps this has to do with the fact that the engine is not on a bracket, and is mounted direct, but no matter. The old prop rules, and the Mirage Plus is a no-go. I pop up on 1 chine in less than 5-7 seconds with the old prop.
