SD20 Saildrive parts

I stumbled across this link to a parts diagram for the lower unit of the SD20 saildrive and thought it might be helpful to someone:

It appears to be a page from the Yanmar shop manual and it includes part numbers. I needed to replace the prop shaft which snapped into as the boatyard was replacing my props. It snapped into because my evil PO had drilled a hole though it sideways for a cotter key. Apparently, he didn't like Yanmar's design for keeping the prop on the shaft. The shaft, not counting bearings, seals or labor cost $509.00 -- ouch! So far, the other shaft seems to be holding together OK.
Moral: Don't be tempted to drill a hole through your prop shaft.

PS: I now have two props -- one folding and one fixed -- for sale. If you are interested in them, give me a call at 317-366-8083.
