Thanks for the pictures! Naturally more are expected.
Yeah, I don't see how a support would even work, leave it as is.
It's hard to tell if the engine is too high till you get the whole thing loaded and try it.
Given the nature of pushing the weight of the motor so far back, causing the boat to be a little deeper in the stern and the deep V of these boats, it's probably close but you have plenty room for adjustment.

Oh, if you ain't paid attention, that motor has locks/supports in the yoke for trailering.
