I have a 21'Wellcraft V20 that will be used mostly in salt water. I do not know in what insistence I would need a trolling motor, but assume since I will be primarily fishing from this boat, I will need one. <br /><br />Does anyone have any recommendations? The cheaper the better as I dont know how often I will really use it. <br />What pound thrust should I look at?<br /><br />Lastly, would a gas power trolling motor be better then an electric for salt water fishing? I will be fishing around Jamestown, Newport, and Narraganset Rhode Island.
