Is this propeller angle right?

[lqbweb]

Hello,

I am starting building a boat. 26'' Mono Hull (640mm), and I am trying to get the propeller angle right at 75mm.

Does this propeller angle look like too much? It is basically on the keel line. I can't make it more flat if it is not by lifting the shaft a bit at the hole (making the hole bigger at the top), as there is not enough room in the hull for the motor to rest lower. Should I do it? There is around 4.5mm from the bottom of the hole to the keel.

Thanks a lot!
