......that there is not overwash? I finally got a good moving view of mine yesterday and it looks to be 2-3" fully submerged at the lead edge. Is it worth it to try and move the main up two holes?

I notice that if my fuel tanks are full the trim is lower in the water at plane than when 1/2 or less in the tanks. Works so well for me so far that I wouldn't think of making changes.

Only my $.02 :roll: But I'm running a Honda 90 on a 19'.
 
On the Tom Cat, the permatrim runs at the surface (no water over the top). I will be putting the permatrim on the C Dory in the next day or so, and suspect that it will be under water at some points of trim.
 
I had a chance to observe the motor plate level relative to the hull bottom the other day in a sling and concluded the motors are not mounted too low. My Permatrims run submerged and I had considered moving the motors up. Fact is, I'm very happy with the boat's performance and have decided to leave the motors where they are. I have lost 1MPH on the top end but can plane several MPH lower and get excellent fuel economy and twin engine lateral trim effect. It works so I won't try to fix it. Mike.
 
From my discussion with Andy at SIM, the top of the Permatrim should NOT be underwater at cruise.
 
With full fuel, and permatrims on twin Suzuki DF40s, permatrims are not covered with water while on plane, at any speed above 15mph. The motors are mounted with the cavitation plate even with the bottom.
 
That's exactly the way my twin Yami 80's are setup, the bottom of my anti-ventilation plates are 1/16" below the plane of the bottom of the hull. The tops of the Permatrims are not underwater while on plane. No problems, even in hard turns.
