From what I see, you can lower the motor down one hole or go up 1 or 2 holes.

Looks like you have the Standard mounting bolt pattern.

At any rate, you would want to look at the cavitation plate when running on plane. You should be able to see the cavitation plate just at the water line or barely above so it is not creating a huge spray of water causing some "Drag".

After reading Joe's post and closer inspection of the photo, I believe Joe is correct, you have standard bolt pattern and are mounted 1-hole up.

31 MPH is not bad, about what I get with 35HP on a PT-35 and stainless prop. What prop are you running? And, check the tach!

From your video it appears that you could try raising the motor.
