Im going to look at a couple of used honda 50 four stroke motors this afternoon, I am running a 40 hp merc right now 2 stroke , figured the four stroke honda would be a upgrade,does anyone have any experiance with these motors? they were in alaska (salt and fresh water) and run for about two weeks a year then winterized and put up for the year. Ill check compression and motors can be run on muffs. its a set of two 50,s on a 20 footer.What ya think?anything i should look for? thanks , jerry.
