Default Motor Height - Raise Engines?

Hey guys,

Took a couple of videos of my motors on plane around 4000 RPMs, they look pretty low compared to proper heights ive seen on ThT, thinking it may need a couple notches. Just confirming with you guys first. Sorry for the short crappy videos.... Thanks!

Very short clips but initial thoughts are the height looks about right. Take a 45 degree turn and if the props cavitate I’d leave the motor height alone.

I apologize for the short videos, I was the only one on the boat and didn't want to leave the wheel unsupervised long lol!

Had to pause and manually move the vid to see anything. Took a few screenshots...they look a hole or two low.

Trim them up and see how far you can go in a turn before they cavitate if you’re able to trim up >40% and still make a sharp turn on plane, plenty of room to raise a hole or two.

The experts here say that you should be able to see the top of your cav plate at cruising speed. I’m too low also!
