Question: Does running two 12v batteries in parallel increase only running time or will it add power as well?
Document: I have not owned a Minn Kota electric motor so I was taking a bit of a chance ordering online especially when I had not heard any reviews of the new Endura Max motors. I took two batteries expecting to troll a lot on the lake and, to my surprise, never used more than a fraction of the first battery! I was amazed at the efficiency of the motor. It pushed my drift boat easily across the lake with three of us in the boat. I highly recommend this motor!
Looks well made and worked out of the box. I cannot say anything for battery life or performance as its still freezing cold here.
I was using a 30 year old Minn Kota, 35lb thrust to push my 16 foot fishing boat. That motor finally burnt up and I replaced it with this. I couldn't be happier. Easy to use and a ton of power.
Make like Nike and Just Do IT. I love it, makes your battery last forever, it's powerful with a great grip that is variable speed and extends. Really can go wrong here. Get instead of the 55 for power draw purposes. Ive had the 55 and it really doesn't make a difference, the 50 id more efficient and a better buy.
My son s looking forward to some good fishin. This motor is powerful enought to haul three &#34;big boys&#34; In his little fishing boat. Couldn't  find this model locally but it is preferred over the newer model.
Answer: no
