Re: more speed

AV plate should be 1 to 1 1/2 above the keel and horizonal to the keel. some go 2 " but watch the water flow. that high and i would want a water pressure guage.

Re: more speed

Might be a little speed in getting it properly propped. You want the revs to be peaking just on the far side of 5500. 5100 is too low, so you'll want to drop a little in prop pitch...
