I have bought a 18 ft. pontoon with 1999 merc.50 that runs great,it has alum. prop F10.13x15p, on the foot is a sticker that says 12x22 1.83:1,
At wot tach is showing 4200 rpm. and gps shows 17.3 mph. Sticker on engine says 5500 rpm, It is time for a new prop and looking for advice on what to use, Being a man I would like more speed,but I do not pull tubes or anything,used solely for cruising,I am looking to do what is best for my engine.Thanks for help.
