Brian,
look at the whole package before you get too many of those motors.
Will you need a gearbox with them? The gearboxes can cost more
than the motor. Is the motor suitable for putting in a housing? How will
it mount in there? Will you need to replace the drive shaft through the 
motor to extend it, or replace it with stainless? No doubt you will have 
to take the drive shaft out to machine in Circlip groves as Stops against
housing bearings, or machining for the propeller .Do you need to replace 
the motor bearings or the brushes?
The housing for it needs to be in sections that bolt together with O rings
and with press fit tolerances for the bearings & seals. A lot of work which
makes a new Minn kota look like a cheaper alternative.
My tiny 3 hp brushless motors have neodymium magnets & only cost
$60- each.
Regards Alan

Talk to them today and they're going to give me three motors for some honey.   They literally have 50 to 60 golf carts in their boneyard with motors at any one time, and they are constantly dumping them into the a giant roll-a-way bin for pick up.  I may try to work a deal with them to get some more.  Most of them are 36 volt.
