Size stud for rocker arms

[ericcarr2000]

Can someone out there tell me what size roller rocker arms I would need to be able to replace the worn out ones on my 3.7 Mercruiser engine, and where I can get them from?
Thanks

Size stud for rocker arms

Can someone tell me if the 3.7 Mercruiser uses a 7/16" stud for attaching the rocker arms, im purchasing some roller rocker arms and need to know what size they are.
Thanks

Re: Size stud for rocker arms

Hi there, Sorry i can't help with the size but thought i would mention it appears the rocker arms use bolts in place of studs.

TORQUING ROCKER ARM ATTACHING BOLTS
IMPORTANT: Torquing of rocker arm attaching bolt must be done with valve In closed position. Failure to do this can result in bent push rod.
1. Set #1 piston at TDC (firing) and torque the following rocker arm attaching bolts to 20 lbs. ft. (27.1 N.m).

Hopefully you have the mercruiser service manual #8 part number 90-44553? because there is more to setting them then what i posted above.

Good luck.
