Can anyone tell me the thrust rating of the 1991 3hp Minn Kota trolling
motor? I bought the motor used, planning on using this motor as primary
power on my 10' Porta-Bote. Unfortunatly, there was no paperwork with
the motor.

I have to agree with the other reply. There is a _reason_ they are
called trolling motors.

A friend has the same boat and first tried using it with his electric
trolling motor. While it will certainly move the boat, it is slow and
unresponsive. He kept that electric for its' designed purpose, but
purchased a 3.3 HP gas outboard for the Porta. It is very effective at
motivating around.

Go look at what they say is the max HP for those boats. Then ask
yourself if the little electrics are going to be useful for anything
other than the local farm pond.

Cheers, Ed

There is a "rule of thumb" that estimates about 30 lbs of thrust per
hp. There are also the laws of physics that require about 750 watts
of power per hp. Since 750 watts equates to over 60 amps from a 12
volt battery, the likelihood of actually generating 3 hp from a
trolling motor is very remote.
