Electric=Cheaper to buy
Gas=better in wind or rough water
Gas=easy to carry spare gas
Electric=never hesitates to start
Gas=mixing oil and fuel
Electric=batteries can be recharged cheaply
Gas=too many parts to break
Gas=can't be bow mounted
Just a few pros and cons to each. As a matter of expense and the fact that I don't often fish big waters I use a minn-kota myself
I like to have both. On windy days I'll use the autopilot to steer and the gas to give it the power to break through the waves. I have a 24 volt system and it lasts pretty long if you use the dual combination. The key for electric is good batteries and charging them as soon as you get off the water.
Thanks for everyones input. I have a 12 volt system but am looking to add an onboard charger with another battery to increase my amps. Cabelas' Prosport 12 put out 12 amps and will distribute on demand different amps to the battery in the most need. With a couple of battey gauges. If I hook 2 batteries in parallel will I need only one gauge for them? I believe that to be true.
