I used to own a pair of 1987 standup jetskis. Before heading off into saltwater, I would cover the carb with a plastic bag and spray the entire engine with wd40. When I got back home, I would flush the skis and then spray the engine down with water and then wd40 again.<br /><br />Should I be doing the same thing with my I/O boat when heading to saltwater? WD40 or something else?
