Hi Mike - i put the same engine on my 4.7 Avon, ran in for 10 hours with the same size prop you have on yours, and could get 35 - 36 knots on a flat calm day, though the Avon is a lot lighter than the 4.8 Ribcraft, i never tried changing props as i wasn't that bothered about going faster, and everything worked well. The Yam in my opinion is a very nice engine, i never had a squeek out of mine in over a year and it still ran like a dream even after being turned over.
