Advice on buying C36

Looking at a couple 1999 C36s but am concerned with the possible camshaft problems due to missing sleeves on the Universal M35. Is this something I should be concerned about this many years after the fact? Anyway to tell if the previous owner installed the sleeve if it was missing in a timely manner. Thought of buying a boat with possible engine problems is a real turn off. Any advice? Really like the boat though.

Universal - the manufacturer of the engine will mail you a free ring if you send them the serial number of the engine. They keep track of which engines have requested the ring.
If they are no longer offering this ring - please contact me and I will ship you a spare one that I have. It goes on M35B engine.
I have a write up here . Download and veiw bulleting 235 

Here is the bulletin below:

On August of 2002 Westerbeke issued service bulletin 235 regarding failure of sea water drive tang on cam shaft on early "B" model Universal engines.

Westerbeke will ship you a new tang re-enforcement sleeve, that is installed on the engine side, free of charge along with gasget for the pump.
Contact Westerbeke by phone 508 823-7677 or email
You must provide your engine model and serial number. For me not only they send the re-enforcement ring - they also send newly edited manuals for the engine all free of any charge.
Here is the PDF file for the Service Bulletin 235
The part number is 48245

You can search this site for info on cam shaft failures. It seems that there are maybe a handfull of owners that have reported the problem. I don't know how long the M35 has been used on the C36, but I would guess it's close to a thousand boats? 5-6 reported failures divided by a thousand is a pretty small number. Even doubled or tripled, it's still a small failure rate.
