ok...got it now...would be more convenient if new topic could be started from the last post of previous topic instead of going to specific forum's home page...but never mind..

Would a 2 blade prop on my outboard-saildrive setup give me even more revs and high end power?

Don't think that's possible to find a 2 blade prop on the market, usually are non through hub exhausts props and you have a through hub exhaust system. OTOH an I/B engine delivers way less wot rpm and torque compared to any OB. So an OB correctly propped to move a sailboat should be more efficient powering it.

Yes. An inboard running at maybe 1500 RPM is one thing; an OB running at 6000 is quite another. The correct prop for this setup is a 5-pitch HT 4-blade prop. Period.
