Outboard on Large Sailboat

Considering a 'high thrust' yamaha (or even 2 if it would help) on a 36 ft large displacement sailboat. Would like information on specs for the yamaha:

Largest Prop / Pitch Available etc. Torque etc.

Boat previously had an inboard diesel - Perkins 4 107
2:1 Reduction Gear
40 hp @ 3000 RPM
Not sure of prop size at this time.

Any other recommendations? - Weight or placement is not a consideration.

I'm more concerned from a performance stand-point. The hull-speed of this displacement boat is approx 8 knots.
 
One of the old Achimedes Penta U-22 or perhaps the British Seagull???
Quite honestly it does not sound like an outboard project.
However there are some diesel outboards on the market.
