| I have a 17 foot flatbotom boat and was wondering if you guys think you could use a dual porous battery for both starting and trolling. I have a 30 pound thrust minnkota and a 40 hp mercury 2 stroke. My only question is do you think I could troll for hours and still have enough battery to start the main engine or do you think I should go with two batteries. Space is kind of tight in the back for two and I would like to get away with just one big optima battery. Thanks |

Location: upper michigan | I would not recomend this. You dont want to get stranded because your starting battery is dead. |

| I agree that it isn't a good idea. It would be less risky if the 40 hp had a manual start option? If space is tight in the back of the boat, I'd look at placing a deep cycle battery somewhere up front and running 6 or 8 ga copper wire to the TM plug.

| My brother tried running 1 battery last year and ended up spending the night in his boat on the wolf. It made for a very long night. I run 5 batteries in my boat and every one of them has a quick dis-connect. I have 3 up front for my 101lb 36 volt trolling motor and I have 2 in the back. One for my kicker than runs all my electronics and one for my big motor. I also ran a hd wire( same gauge as a jumper cable) with matchng quick dis-conects so I can jump any battery from the front to the back. |

| In my very first boat I had a 35 Evinrude and a transom mount electric and I used a dual purpose battery. I did not have a pull start on the motor, but I could wrap a rope around the flywheel to start it if necessary. With the 40, you should be able to do most trolling with the main motor anyway, so as long as you get to know how long you can run the electric you can certainly get by with one battery. As mentioned above though, it isn't the safest way to go.
