I am a little lost in the way you guys talk about boat motor power. Gas motors, you give their power in HPs, thats easy, easy to convert to Kw and of course to PS (metric horsepowers). Now for electric, troling motors you use, if I understand right, lb of force, pounds of force. What is that and how does that convert to metrics? I have been looking for the answer for a while and cannot find it. It seems to me more logical to have electric motors be measured in Kw, it would make it easier to judge battery life out of that. Also, I see some ald outboards on john boats that are 10 HP and they are very little. Than I see some new (but 2 stroke) 10 HP outboards and they are just huge, not much smaller than 225 HP standing right by it. How strange?
