I have an 18' bass tracker w/ a 90hp merc. I have been using an older motorguide 45lb 12/24 for the past few years and that motor is beat to hell and on it's last leg so I just bought a new motor guide pro series 24v 75lb. I liked the old 12/24 because I fish in drastically different situations and the wide spectrum of power options came in handy. If I were fishing in heavy current (tail races), I could use 24v and mainain control and move around...but if i fished above the dam at night when there was no wind, I could put the motor on 12v and creep along in stealth mode,,,some times speed 1 on 24 was too fast when the water was dead calm. I fish the tailraces more times than not so the high power is needed so thats why i bought the new 24v motor guide. My question is can I install a toggel switch on the bow where in the top position I could run 24v and then in the bottom run 12V? it looks like to me that on my old 12/24, the toggle on the pedal just simply ran the motor to one battery in the 12V position then switched it over to both batteries in the 24v position. I guess the bottom line is, will it damage this new 24V motor to run it off of one 12V battery?...or is there something about the older 12/24's that allows it to safely run in 12 and/or 24?
