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".
