We was sitting around last night and i thought of a good one.How many lbs of thrust = 1 hp .Say if a trolling motor has 54 lbs what would that be in hp ? Mich

Well it seems that your not the only one. I didn't write this, it made me dizzy :dizzy: , and I think I will never wonder about this question again.

We know that by definition one HP is 750 watts. If a trolling motor consumes 20 Amps at 24VDC to generate 50 lbs of thrust it consumes 480 watts in the process (Amps x Volts = Watts or AxV=P).
So it would be approximately 480/750 HP or 0.64 HP.
A 24V trolling motor system would consume 31.25 Amps to generate 1 HP regardless of the thrust it generates. That is:
750W/24V = 31.25 Amps. P/V=A
The greater the thrust generated at 1 HP the more efficient the motor is.
(I made up the numbers just for the example of the calculation so check the spec sheet for your trolling motor to see how much current it draws at the specified voltage to generate the specified thrust.)
The benefits of an electric trolling motor vs. a gas motor are discussed quite well by others who answered your question.
Good luck and good fishing - the Fisherman
