I was curious about the availability of the cams after I saw Gary's post, and decided to call DEPCO to check on the price and availability. I spoke with George at 1-800-446-1656 and he knew exactly what I was looking for. They have a bunch of them in stock, amazingly enough for a 40-year old part, and the price is $33.12. While the price may seem high, it's a critical part and without it you may be faced with buying a new pump (hundreds of dollars).
Here is some info from the DEPCO web site and their catalog, for the Chris Craft Commander owners ! (thanks DEPCO, and thanks George!)
DEPCO can be reached at
