compression on 50hp 4stroke mercury

[bitsy4643]

what should compression be on 50 hp 4 stroke mercury? 155 lbs on all cylinders. is that low? Dealer replied should be over 200 per cylinder. Thanks

May depend somewhat on the year.

My service manual for 2002-on says 180-210 psi.

Are you confident your compression gauge is correct?
