Hi Brad,

Try to get the propshaft as parallel to the keel line as possible.
If the boat sits on its keel on a flat surface, there should be 2-3mm of air between the prophub and the table.
Distance between the transom and propnut: generally 10 - 12 % of the hull length

Depending on how much power youre going to install, the less angle, the better.

Short of installing a flexshaft, or wire drive, this means a (very) long solid shaft to get the motor as far forward as possible without compromizing the CoG (28% from the transom).

Regards, Jan.
