have a 40 lb thrust Minn Kota that I want to use as a side pulling, secondary electric motor. Don't want another heavy deep cycle battery in this 16' tracker. Saw this one on Amazon:

 

Light 12V Battery

 

Would this be a waste of money, or would it work for slow side pulling this boat for a few hours? This battery had some great reviews. It also had some not so great. Not looking to run all day by any stretch. Thanks guys!

I use a similar one on my MotorGuide 45 (Wilderness Tarpon UB12350) also available at Amazon at a similar price.

It runs fine for about three hours trolling speed.

I bought a similar batt at Batteries Plus locally for my

30 pound thrust MinnKota on back of my kayak. I can

go for hours! Never been depleted yet.

 

Methinks it'd do what you need.

I should also note that I use mine on my 10 foot Portabote which weighs 80 pounds empty so a heavier boat should get less hours run time I would assume.

 

I just grew tired of lifting a 65 pound deep cycle battery in and out...age certainly has its effect!

Thanks so far guys.
