I'm having an early Merc triple bored out .030 over and need to tell my boring dude what clearance I want.
Looked in my genuine Merc manual and couldn't find it. Anyone have a spec?
Thanks,
Jeff

Thanks. I guess a little loose is best for racing.

factory is about .004 on cast pistons, a forged piston is going to grow more than the cast bullet when at running temp, so more clearance is needed, about .008
Thanks!
Happy Thanksgiving to all!
