I was wondering if anyone out there would care to share their
experiences with the Campbell Sailor three bladded prop.

We currently have a "traditional" three bladed prop and get black
smoke at high rpms. We are not able to get the maximum rpms our
engine is rated for (Yanmar 3GMF). Several people have suggested
that we are over-propped and the Campbell seems like an
attractive replacement. Are are still exploring other possible
causes for these problems (suggestions?), but the propeller
problem seems the most likely.


Has it always been this way, or is this a recent problem? Have you
checked the injectors?

If it's recent, it's probably not the prop. Otherwise, if you're
otherwise happy with the existing prop, just re-pitch it. I have a
Campbell Sailor on Far Cove, but I have so many other problems I can't
judge the prop. I've heard Good Things and Bad Things. If it means
anything, I'm almost sure I'll be getting another Campbell Sailor
when I get my new engine. (And they're built right here on the West Coast,
so I like that!)

If you want to put out the bux, my other alternative is the AutostreaM -
it's a feathering prop that you can easily adjust the pitch, even
underwater. But it's $2500 CDN...
