I saw in one of the threads a discussion of pink color on prop shaft. I have some pink on my shaft prop and cutlass. What does this mean?

Check the prop blades for dings, chips or dents. Inspect the blade tips for signs of electrolytic action. If this portion of the prop looks corroded, immediate attention is required. It may take hiring a good marine electrician to find and correct the source of this electrolysis or galvanic corrosion. If the prop surface appears uniformly pink, dezincification is at work and essentially your bronze propeller is turning into a useless piece of soft copper. The prop should be replaced, as its structural integrity is questionable. Again, the source of the electrolytic action should be located and stemmed.
