[C320-list] Feathering Props

[sailorlew at aol.com]

I have a 2 bladed Max Prop & asked the PYI rep at the Newport show why the 3 blade model needed the zinc attached to it while the 2 blade didn't. He said that if the 3 blade model was not installed in an apperature with no room for a shaft zinc, all you needed was a zinc on the shaft to protect it.

Ed,
In stead of bottom paint you can use finger nail polish (color of your chosing).  
We've been doing that for the last few years and the zinks have been doing a 
much better job of staying tight.

Our boat has a MaxProp and we have owned the boat for 4 years.  It has been
great problem free, backing port or starboard is no concern especially with
our turning radius.  The prop always feathers, I check periodically when
racing.

The only problem that I have noticed is the propeller zinc.  We are in a
fairly hot marina and I change zincs at 8 months.  The zinc around the
anchoring bolts is the thinnest part of the zinc.  Once the zinc had fallen
off due to corrosion,probably.  Other times the zinc is usually near
failure.  Last Spring I had the bottom painted professionally and the shop
recommended that they use bottom paint around the bolt holes.  I had a diver
clean the bottom and check zincs two weeks ago.  He specifically checked the
prop zinc to see how the bottom paint was working.  The area around the bolt
holes is holding up and the zinc is being  (eroded, corroded, electrolyzed?)
used up.

>From this experience I recommend using bottom paint around the bolt holes if
you are having similar problems.

If anyone sees a problem with this please let me know, I don't need to add
to my list of headaches.
