I have a Minn Kota trolling motor that is rated for 24 pounds thrust to power my dinghy. Does anyone know about how much horse power that is. For example, would a 2 H.P. gasoline outboard give me more or less performance than the Minn Kota that I have ?

HP = volts x amps / 746
1 HP = 746 watts. Watts = Volts x Amps, but output power will need to be derated from input power by some factor for losses.Perhaps the motor will be only 80% efficient - not too sure about the precise number. Thus - you can get an idea from the input power - from volts x amps, the output will be a bit less. Minn Kota specs or website can probably give you the amperage draw of your motor. 24 lbs is likely to be a bit weak HP-wise, maybe 1/4 to 1/3 HP as a guess.

Not again.
The non-scientific rule of thumb to compare the performance of an electric trolling motor to a gas powered outboard is that 75 pounds of thrust equals 1 horsepower. Scientifically there is no conversion between these two ratings as one is a measure of work and the other a measure of static force. Check the archives for a well documented exercise in futility. The short is that your 2HP will perform better than any trolling motor in the market.

thanks
thanks, Benny, Ross, and Old Cat. Just got back from a weeks holiday on the boat. I got to see what you all said. My trolling motor was outperformed by a 2HP Honda. The big difference was in motoring against waves and wind. Think I will put the Honda on my wish list
