Well, I've finally gone to the trouble to identify my transmission – I was replacing the potable water hose to the heater/manifold. From what I can tell, I have a Warner. Does anyone know anything about this transmission?
Thanks,
Bob

To my knowledge, Pearson installed Borg Warner Velvet-Drive transmissions on all 424’s, though they may have put something else in the first couple of production boats. Copy down the information on the manufacturers plate and send it out to us along with a photo of the transmission. If you have trouble reading the plate, rub it with a dry-rease marker and polish it slightly with paper towel to reveal the stamped information.—

Hi Rich,
They also installed Hurth (can be left in reverse or freewheel when sailing) and Paragon (Maybe, maybe not can freewheel), and the Borg-Warner Velvet Drive which can freewheel in neutral. The Paragon might be a replacement tranny.

Actually the Paragon was the original tran (on hull #2 anyway). The Velvet Drive is still in production, although not by Borg Warner. I installed a new Velvet Drive when repowering over the winter to a Yanmar. It appears to be the only direct drive tran still in production suitable for the 424-sized engines.

Bob-
Depends on if you have a W-60, or the later W-58. Westerbeke told me that Pearson specified Warner Velvet Drive 71c trans on all W-58 engines.
This is still available new or rebuilt and is based on the old Chevy Powerglide. Here is a link that I’ve found useful for both the trans and the Walter V-drive:

Hi John and Quent,
It is, indeed, a 71C or 72C (I still haven't found the plate). Chevy Powerglide? That was a two speed tranny. I had one on my 68 Impala. It was a total misnomer. It wasn't power anything. It was the definition of 'slush box'. But I digress.
Anyway, the point of this whole discussion is that the all Velvet Drives can freewheel. That's of huge importance to me because I plan to use the shaft power for an alternator. I've discovered that the transmission output shaft runs at about 100 rpm/knot, so that at 5 knots it's running 500 rpm. That means a 3:1 pulley system will handily turn an alternator at 1500 rpm, comfortably above the 1200 rpm or so it needs to start generating power. The output shaft runs a little slower, but would be more powerful.
So, this is do-able with some clever engineering including those new link-type belts.
Stay tuned!
Bob
