• How would you stop a prop from turning?
  • Yanmar in reverse
    • Yanmar now says no on reverse.
      • Use forward then . . .
      • any more on this? why?
        • Me too. With no problems (as far as I can tell...)
        • I called Mack Boring...
        • Apparently it is a recent thing, and may only affect certain Yanmars
        • Mack Boring's advice
          • better to let it spin in neutral??
  • It's called a shaft brake
  • With a Max prop (or Flexifold Gold folding prop), you shouldn't get any spin
    • So with the right prop, don't worry about it, eh.
      • When working, any feathering or folding prop should "de-tune" itself
        • Got a web site for Flexifold Gold...
          • I can't type: Flexofold - http://www.flexofold.com/
        • Feathering NOT
          • Do you have any info on that shaft brake?
            • Nice pictoral
            • This is what we have.
          • Our Max prop doesn't seem to rotate at over 9 knots
            • Two or three blade?
              • It's a two blade -- but I believe the three blade has the same general individual blade shape?
            • Our 3 blade MaxProp doesn't rotate
          • Depends on the type of feathering....
            • Perhaps I'm misunderstanding you, but my experience with the Autoprop is the opposite...
              • Hmm, that means it is in reverse pitch...
          • What happens with the Shaft Brake if you should accidentally put a running engine in gear with it engaged...?
            • Ahh, just saw your link above, that answers my question... releases automatically, that's pretty slick
            • I would imagine.....
  • The guys in Maine use a lobster pot or some fishing line wrapped around it. Keeps it from spinning every time.
    • A auto-rotating (spinning) prop in Maine is a VERY BAD thing -- even with spurs.
