We used a minkota 55 lb thrust electric to get out to our dinghy
in the CT river, we had it on a 10 foot Zodiac
. We had two batteries, one stayed on charge in the boat (we have solar
panels). It was designed for salt water
and worked great. Although we did have a couple of occasions were the tide, wind
were all in harmony and we almost did not make it back to the boat. That is when we decided to buy a 3.5 Hp outboard
. If you are in an area that is better protected it may work for you. We loved it, quiet, no gas, always started. It would last for days but just to stay on top of the charge I generally changed everyday even though it did not need it. I was less than $300 dollars at Walmart.
