I have a small (12ft) fold-a- boat and wish to purchase a motor for it. It will only be for getting to a fishing spot and maybe trolling. I am looking at both a Minn Kota electric with 34lbs of thrust and supposedly 10 hr running time and a 2.5 HP mercury. I am leaning to the electric for the much quieter engine but like the other for the better speed. Are all electrics ok in saltwater or are there specific salt use motors?<br /><br />Thanks simon
