Can anyone tell me how a 50lb thrust trolling motor would compare to a small outboard. How many horse power would a 50lb or up trolling motor have. I need a motor for a small 10 foot jon boat. Would I be able to get a good speed with a trolling motor, and whch size should I use?

This question comes up from time to time, Fishman. There are no direct answers. I can give you some vague answers.

A 50lb 12volt electric with energy saving control circuitry may draw 35 amps at full speed. That is 420 watts, or a bit over a half horsepower. Even the smallest outboard is more than 4 times that.

That same electric could probably move a lightly loaded 10' Jon at 5 or 6 mph.

The electric would be very quiet and very easy to start and control, but would require a heavy battery or two, depending on how much it will be used between charges.

A 2 stroke 4hp outboard with gearshift would be able to move your boat 8 to 12 mph and run all day on 10 pounds of fuel. A small 4 stroke, like the Honda 2hp would be quieter and use even less fuel.

You can rig your electric for less bux than an outboard (unless you fall into a terrific deal on the engine).

Hope that helps.

JB gave you excellent advise. Here is my limited experience with electric motors. I have a 13' Whaler (probably about 900 lbs. loaded) with a 34# thrust electric motor. It probably pushes us around at 2 mph. I really like it. The only problems I've had is trying to go against a good tide or strong winds, thats when a motor is nice like JB recomended. Electric is a nice backup but a gas motor would be my first choice, depending on the water and conditions you are fishing on
