I have a 1989 Yamaha Pro 50 and was wondering if there was a way to hook up a permanent mounted engine flusher, the type where you just hook up a garden hose to a hose bib on motor and turn on? My buddy has a newer Yamaha and has this feature factory built in to both his main yamaha 125 and kicker. This is an awesome feature when you are frequently going in saltwater. Also have a 1989 8.0 hp Merc kicker would like to do this to both motors especially since I have to carry 2 motor flushers around for both motors, Merc has a funky mount under motor cav plate. Sorry if this has already been asked had no results when searching this. Thanks8)
