[PSUBS-MAILIST] Fw: motor

Mon Oct 3 12:23:23 EDT 2016

looks a good find Hank.  How do you know the controller is in the motor?

"equivalent to 5hp"   right.  But the other specs sounds good.  24v works
for me...

Be interesting to see what they are like if you get one.  Id like to
upgrade my aft motor.  This could be the ticket...

regards
James
