Re: Confused about prop pitch, variance between prop brands
Can you quantify "long"?
My prop shaft is about 3'. It is 1" in diameter. The longest unsupported section is under 2' (between the stuffing box and prop support) as shown in the photo above. Those are standard 1" zincs.
As I said there was no noticeable change in vibration when I went from Michigan Sailor 2-blade to CS 3-blade.
Looking at a drawing of the CS 36 T it looks like the prop shaft is setup to be more sensitive to vibration. The V-drive arrangement makes it have two sections of close to equal length, one inside the boat and one outside. The prop shaft is also longer due to the V-drive arrangement, but it is still 1" in diameter.
I understand that the folding prop makes vibration more likely. A feathering prop would for the same reason that you mention. However there are many happy users of both as well.
