Are all TRS/SSM dampener/drive plates splined the same for B/W transmissions?
How about old MercTrans TRS drive plates?

The old 330 trs with Merc trans. and the 370/400 TRS with B/W trans both show the same part# (860125T} but that doesnt mean they are. 30 years of #,s superceding things do get scewed up sometimes.

All the BW are the same as far as the spline but big differance in quality/capacity on various plates, the Merctrans plate is differant (and hard to find)

Thanks.

These are two entirely different species and not interchangeable. Borg Warner used the same spline count and pattern as Volvo Penta I/O, and these are readily available. The MercTrans plates are a species unto themselves and are difficult to find...www.kcmarinetr.com has available MercTrans plates.
