It might roll of the tongue nicely but at maximum torque your engine is only delivering about 5 hp to*a "well matched"*propeller.

Why not just install an old Briggs and Stratton and save a few tens of thousands of dollars if all you want is 5 hp?
!600 rpm (about 10 hp)*will theoretically,*under ideal conditions, result in a speed of 1.2 times the S/L ratio which the Coot's*designer finds desirable.* More power/rpms will be needed for less-than-ideal circumstances.* Leastwise, the designer and builder believe it important the boat*has much*more than minimal power available.
