I'm starting to think about mounting the strut/motor etc.

I have the depth of the strut on the plans so I think I know that, and I know that the prop needs to be partly under the transom front to back, but what angle does it need to be on? In the plans it's on a huge angle (see below) but everything I see elsewhere has the strut basically flat with the running surface.

I assume then I mount the motor per the mount (which has some adjustability) and go straight out of the hull from the motor, and bend up to the level of the strut?
