Prop slip??
Hey guys, wondering if my x-dem is to high on my 1984 wellcraft excalibur. Here is what I have....
5,300rpm, 1.50 gear ratio bravo one drive, 28P bravo one prop, 75mph gps. I came up with 20% prop slip. My X-dem is 19.5in and the prop shaft center line is only 2 3/8in below the bottom of the V. Should I put a spacer between the upper and lower unit to get the prop down more in the water?
Thanks
Erik

The true pitch is 27ish. As Griff said, not alarming but still high. Good prop work would be a great thing in your case. If done right, some of the slip could be used to add speed and efficiency.
