I have a 1993 20hp 2stroke merc that is currently running a aluminum 13 pitch prop and it's on a 1648 alumacraft flat bottom jon boat.The motor will get it,has awesome power so i believe i have the right prop on it.The question is i was thinking of going to a ss prop but i don't know for sure but i believe isn't the rule of thumb to drop a pitch going from aluminum to ss? How much increase in speed could i really get by switching to a ss prop also?Is it worth the extra $100.I know a ss prop will outlast an aluminum one by many yrs from what i have read.I could use i mean a hair bit more hole shot if i had to complain about anything i don't like but it's not that bad.I love the wot performance, i get near 30mph with close to 1000lbs in the boat,that is just amazing for a 24yr old outboard and a 20hp to boot.I am thinking of either staying with a new 13 ss prop or going to a 12.Any help would be awesome,thanks.I just want to know what to expect if i go either way up or down.Most of the time it will be just me or me and a friend so that is all the weight.
