[QUOTE="richg99, post: 424292, member: 4376"] Just trying to learn something here. The prop chart that I looked at for a 15 hp 4 stroke 1989 Evinrude said 5500 / 7000 rpms https://www.rubexprops.com/boat-propellers/rpm-range/?make=Evinrude So, when sizing props, does one always try to max out at the 7000 figure? If you were "in the range" would that be sufficient? It seems that the OP has a 27-year-old motor that is running "OK"? Why fix what isn't' broken? I readily admit that I know darn little about prop sizing. Never changed a prop in the many boats that I owned, other than to go to Stainless after ruining too many aluminum props on the oyster reefs here. I was never concerned about maximum speed. richg99 [/QUOTE]
