i just buy a new cmb 45hr and i want to know if i need to shim the head or it's correct from cmb

i look and i have only 1 shim and i think it's .08

How many shim i need usully

i think normaly the guys put around .12 is it right.....

My hull is Hydro 45

Thanks

Pat.
 
How many, and the thickness of the shims depends on what your head clearance is,

You would have to check the distance between the top of the piston at TDC and the distance the head button sticks down into the sleeve.

But you are correct, .012" sounds about right for a 45 in a rigger
