Many Thanks to both respondants.
So even with an aluminum prop I could arguably gain from a drop in pitch, and for Stainless Steel it is certainly the right thing to do - yes?
The Yammie https://www.bhg-marine.co.uk/yamaha-...ller-108-p.asp
is actually what I have now, but one of the blades is noticeably bent.
Just for my understanding, if I went for this prop on ebay should I expect 200RPM more or so at WOT and would that translate to slightly higher top speed (maybe at the expense of low end grunt) or more likely much of a muchness?
