You will need to move your transducer to a better location or maybe to high or to low. I had the P66 on my 588 and now the 1kw and both read over 30knts. try up and down first and see where it sits in the water.
I have my mounting bracket down on the transom edge so a couple centremetres lower than where yours is and I get a good pic up to and over 20knts. Lose a bit when it's rough but I think most would.
My suggestion would be follow the Airmar installation instructions to the letter, this should give you a bit of a baseline to start with.
I remember doing something similar with a TM260, a small amount of time with a ruler/straight edge to set it up as Airmar suggested was worth it. The shape of your hull looks like it should produce clean water.
I'm assuming you lose bottom on both 50 khz and 200?
A bit of tinkering should see that setup perform really well.

Mine stop further forward but are still there and can effect the picture.
My p66 was mounted higher and would give a good picture at 30knots

I would agree with tim looks
I would agree with tim looks a little low. Have a look where it is sitting in the water when your on the plane.
