I have a 3 blade Campbell Sailer 13" diameter x 7" pitch for 7/8" SAE Std. taper shaft (2QM15 engine) which I'm happy with. I switched from a 2 blade MW prop. I get more RPM, less vibrations, and I can now hit 6+ knots in calm conditions....

I did not do that right- though I do think there is more of an issue be it our boat or not- i will look at the Campbell sailors and flex -o- fold- I am scared what this will cost me- oh well my kid can pay his own way through university in the future!

I see you are from Hamilton, we are in Burlington – where do you keep your boat? Perception is at Newport in the summer and 50 Point for the winter ..... we use a magnesium anode (better protection in fresh water than a normal zinc anode) and it gets chewed pretty badly after just 1 season ... trying to find the cause but no luck so far – I’d rather replace the anode than our prop though! I might look at a Campbell sailor 3 blade, found it better than the 2 blade when we put it on, felt like less drag, less prop walk and more power when we needed it ... but like the Flex-o-fold even better.

Couple years ago we bought a 1980 C&C 30 MKI from the original owner. wonderful wonderful boat! This was our first boat and things have been a bit daunting at times- but I cant tell you how much the list helps. When we pulled her this year we had some serious prop corrosion issues. We are still trying to assess the cause (anode was replaced last spring but perhaps I didn't get good contact)but regardless we will need to replace the prop. It is a 15 inch radius 2 blade fixed but the erosion is such that I cannot read the pitch- how do I figure this out? Any suggestions as to suppliers as well?- we will likely stick with the 2 blade fixed. has any one had experience with the urethane perfect pitch props?
