I had a Minnkota that I used on my dinghy. When we were properly anchored,
we launched the dinghy to go ashore and put the little Minnkota on, hooked
up a 40 amp/hr battery and off we went. Worked great, however, a word to the
wise:
The Minnkota model we had was a 39 amp/hr motor and the battery was a 40
amp/hr battery (the lightest, and cheapest, we could get) so a little math,
and presto - you got about an hour of motoring in that dinghy (there were 5
power settings and we NEVER used #5).
Your own usage may vary.

Both Minnkota and Motor Guide produce electric trolling motors big enough
to use as auxiliaries on small sailboats. Has anyone tried running these
motors as generators to charge the on-board batteries? Does anyone know
the motor configuration (permanent magnet, shunt wound, series wound)?
