Just bought a set a couplers,for a bravo drive they showed up today.They are the kind that bolt to the center of the fly wheel with studs that hold the coupler and flywheel on.ARE they really for a bravo.I never seen theses on a bravo big block boat.I have seen them on a alpha and a bravo small block boat.I called the man I got them from and was told they came of of 502's.I believe him, and we agreed on a solution but NOW I want to know for sure what this type actually is,I could be all wrong,and If so I can accept that SOME ONE give me the application of these couplers.They are 4 7/8"in dia. Thanks JOHN SR

the coupler you describe sounds like the one used on the early drives .
not intended for H.P. engines .
can you post a pic??

Never seen a Bravo coupler like that and I would never install a used coupler anyway.

The guy is giving it to you on the chin,,those are older mr couplers...could have come off of 502's but for a omc king cobra or volvo penta sx drive but definitely no a bravo coupler..

if they are dark grey then they came off of a omc and are for a king cobra drive..

check bolt pattern. are they 1-piece or 2-piece seal couplers?
