correct angle for a drive shaft with 2 joints

[gn7]

Hes a re rig new stringers no holes and yes I get strut angle versus v drive with a exesting strut I talked with Michael today on the phone and figured you would have some good input also. He thinking his v drive may lean 2 degrees forward .

His V drive angle is what the prop shaft angle says it its. No matter where the box gets mounted, the top shaft angle is going to be whatever it is due to the prop shaft ange. He could put a prop shaft in it that 4ft too long and the box is on the deck, the angle of the box is the same.

Where the box falls in the boat is determined by the shaft angle as well. You can move it forward, if you move it up like 2MM said, but who does that?
If you with the prop location, which is where you should start, then the v drive is where it is. When they used to sell stage one boats they had the strut installed. You didn't need to know where to put the box, it just went on the other end of the shaft.
Now if we move on to the engine, and decide it goes here>>>>+<<<<<<< you have really narrowed down you abilty to change the drive shaft angle.
Strut position and angle---check
v drive location and angle --check
engine location----check

so we are left with engine height, up and down(until the pan hits the floor), and tilt.

This is a MoPar RB. Odds of him getting the engine too low are slim and zero, so that leaves him with how many options to mess with drive shaft angle. Get that ONE remaining part wrong, and its the difference between a u joint that last a summer, or 10.

OR,..........we can build the entire boat around the idea of the perfect u joint angle.
