As to the props, what TheFermanator said is good advice. Just remember if switching to a SS prop that SS flexes less than Alum, so normally you move down a pitch or two when switching. (So a 17P Alum becomes a 16P SS).

His current prop is an OLD MERCURY 3 blade 18 pitch aluminum, I would expect a 2-5 mph increase in speed with most any decent stainless prop over an old tech aluminum. Aluminum has gotten better through the years, but his aint one of the better ones.
