Another Motor Mounting Hole Question

[Michael Joseph]

I feel like my motor is mounted too low on my 2018 GCW with a Yamaha 150 HP. Looking at the attached pictures, what are your thoughts? I feel it it should be up 1-2 holes to help efficiency and speed. My top speed has always been just bit low at 37.

Such a give and take issue with no answer that is correct for everyone.
You will obviously see a speed increase with every hole you raise it. But with every hole you raise it it will cavitate more easily as well.
Mercury "Auto Trim" seems very intriguing to mitigate the cavitation.
