Chief,
I had a Bukh DV20 until I repowered a year ago. All parts are available from Bob Bain at North Jersey Marine, rbainnjmdiesels@hotmail.com, .hmmessage P { margin:0px; padding:0px } body.hmmessage { font-size: 10pt; font-family:Verdana } 973-667-1730, in Clifton, NJ. Also from LSM Diesel (LSM Diesel A/S - Denmark - Marine Motor Sale, Spares and Repair) in Denmark, but their shipping prices are very high. It's a great engine--mine lasted for over 24 years.

Just noticed Chief's post was from a year ago. Maybe the parts contact info will help someone else.

I had a Bukh DV20, great engine for 28 yrs. The water pump">raw water pump seal failed, sea water got into oil - engine seized. Now have Kubota. Seems a common failure.

The waterpump should have a drain hole so if the inner seal fails the water runs out as a warning and to stop contaminating the oil, unfortunately sometimes the hole gets blocked with paint, so as a precaution you should inspect the pump when servicing and make sure the hole is clear. I bought new seals from Eriks a specialist seal company for £1.00 (Aprox $1.20) this year.

I know that now from the post mortem. 20-20 hindsight. Other than my failure to realize what was happening, it was a great engine.
