>..... there are a certain series of Borg Warner Velvet Drive >transmissions used with the Lehman 120's for which there are NO replacement >parts available what-so-ever..... As it happens I have a 17 year old dead Velvet Drive on a 200hp Perkins at the moment. Model #10-14-000-008 I believe. Anyhow, after some searching I finally got a local big name company to look at it and give me an estimate to rebuild. The answer came back $6-11K which rather stunned me -- both the size of the estimate and the range of it which they couldn't pin down without opening up the transmission. In the process of discussing things with them they told me that the $4-8K of the estimate was to send the unit back to Borg Warner for rebuild. Further they told me that while Borg apparently still makes the clutch parts for the unit they don't make many of the gears and various other parts anymore. He said that Borg goes all over the country buying up dead transmissions that they can take apart to salvage gears, etc., from for replacement parts. The big variation in the Borg price estimate is based on whether it's just the clutch parts that need to be replaced or whether gears etc which they would have to find and/or make by hand. As you might expect, I was unenthused about paying that much or about the wide range of unknown cost. I found someone else I trust who will rebuild the clutch in his own shop here for substantially less money and he was a bit astonished that the first place wanted to send it to Borg directly anyhow. Every outward sign is that it's just the clutch slipping. The starboard transmission was replaced a couple of years ago by the previous owner. When I bought the boat the engine surveyor told me the port transmission looked like it was running well at the moment, but that with the age, hours and type of service put on it, that it would die soon. He didn't know whether "soon" would be tomorrow or in two years though. I now know the answer.... Bill
