who sell a good one ???

mercury.

I have a local company we source other power transmission products from looking into making them for me. There are 1000 hp one's on the market but $600 is ridiculous for a clutch disc without linings.

I'll keep you posted.

Merc part # 861523A7. Steel HD coupler with long snout.

Isn't that the Bravo coupler?

I was assuming he was looking for the drive-plate style for the transmission application.
