WB, I just moved mine to the third hole, 2 holes above mounting bolts. I am running the sws 2 19p. Really seemed to help all my issues. I was running at 5900 rpm, now spinning 6100. Cavation plate went from completely buried to running just at or slightly below the surface. I didn’t really have a long distance to wring her out, but did manage to a fuzz over 55mph. Hole shot was pretty good, 0-planing in 4.2 seconds. I beleave my mpg numbers were a little better as well, as I was able to run a little more trim at slower speeds. I could only find some 2′ waves to run in, but felt it did a good job holding nose up. And this was all done with a full livewell.
Tried out the Tempest Plus 21p today, conditions were 75 degrees, west wind 17-21mph. Could not find any water that would let me run up past 40mph today. Hole shot was about the same as the sws2 19p. Was able to go out and play in the rough stuff, found some 2-4’s to run in. Tempest did well, no complaints. Just my feeling, but felt that the SWS 2 19p just, well felt better in the rough stuff. I would like to try the Pro series 21p that Joe is running, and a Bravo 1 FS 20p. As far as your cav plate, everything I have done in the past has been, the starting point is to put the cav plate even with bottom of boat, then check it to see where it is at. We have step transoms, and they throw a wrench in for me. But I think I have mine set properly. My last boat was a Starcraft 2050 w/Etec 225 HO. It drives very differently than my Skeeter, I don’t think these Skeeters like as much trim as I am used to using. Get somebody to drive your boat, fill the livewell, have them run 35mph, trim up where you are running good and look over the transom and see where your cavation plate is in relation ship to the water surface. You want it as close to the surface as possible. For me, I beleive I have it set pretty good. Good luck.
