Would like some a advice on buying an electric trolling motor. It will be used on a 12 food inflatable to begin with, with other possibilities in the near future. I plan on getting the salt water version because it is likely to be used in bays and sheltered water in Canada/Alaska. Should I get a 24 volt system or 12 volt? Is it possible to get too big a motor? Would like to extend my cruising range as much as possible.

Thanks for any input.
