No jack plate. Vertical height has very little effect at displacement speeds. 4 bladed props aren't usually available for small outboards but if the motor offers a "sailboat" prop with larger area use that.

The Mercury and Yamaha both come with propellors the Mercury a 4-blade the Yamaha a Hi-thrust. The Yamaha is also built stronger for longer life. Tom
