Proper radiator cap for 3.7L

[psdscoot]

What is the proper cap for this motor? What is the psi? The one that's on it is a vented cap, the overflow is full and not flowing back when the motor cools.

Depends on the vintage motor either newer (14 psi) : #26 http://www.mercruiserparts.com/Show...EXHAUST+MANIFOLD+AND+EXHAUST+ELBOW+(ALUMINUM) or older (?? psi): #31 http://www.mercruiserparts.com/Show...+MANIFOLD+ASSEMBLY+AND+EXHAUST+ELBOW+ASSEMBLY
