Re: RPM question

WOT RPM's will depend on your prop diameter & pitch.

A typical factory prop that came with that motor & outdrive package should give you a top-end RPM of about 4500, and I believe that motor redlines at about 5000 RPM's

This was actually from Sea Fever by John Masefield, but Star Trek did bring it to millions more than the author managed.
