Steve Blackman told me when the wake starts even with the helm seat the trim is right with the tilt at -5. I cruise at 3200 rpm and count to five seconds on the trim switch this gives me 17kts at 2.5 knot mi per gal tilt at -5.Play with the tabs at a good rpm and find the sweet spot.I think every boat is different because of weight and hp.I think the same for the down swell handeling.I remember the learning curve well by the end of summer you will be a pro.
