After wanting a boat for many many years this is my year to get one. Trouble is I have never been around boats and can count the times I have been in a power boat on the fingers of one hand. I will be getting a used aluminum jon probably with a side console when I can find one. One of the things I have encountered while looking a boats and motors on the inet is that sometimes they will mention that it is a freshwater or saltwater boat/motor. What are the components which make a motor "saltwater". I am assuming that a "freshwater" fuel motor or trolling motor could be used in saltwater occasionally if they were properly washed or flushed afterwards.
