Guys,
Does anyone know the HP equivalent in lbs for trolling motors? (Gas vs electric) I came up with some answers on Google but unfortunately they are different.
On the link below

After a lot of formulas, the answer to the question is:
“Upon further investigation a 1 HP trolling motor=58 to 60lbs thrust at max RPM depending on motor efficiency. “
However, I found the info below on another web site
“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.”
And from another site I found
“That said, an approximation based on power consumption would be:
Volts X amp draw=Watts
Watts/746 = HP
So for a 101:
36 Volts X 46 Amps = 1656 Watts
1656/746 = 2.22 HP “ (45 lbs)
I also read somewhere that one HP on a gas engine = to 200 LBS on an electric trolling motor and almost everyone thinks the answer is 15LBs
So our options are:
One HP = to
a- 15lbs
b- 30lbs
c- 45lbs
d- 58 to 60 lbs
e- 200lbs
What do you guys think.
All this started because I need to buy a small gas outboard. I should just buy a 9.9hp and get it over with. :shock:
