THESE CYLINDERS WERE TESTED AT 80 LB COMPRESSION IN EACH CYLINDER.  UNKNOWN WHAT THEY LOOK LIKE IN SIDE I DID NOT TAKE OFF THE HEAD TO LOOK 

ALL PARTS ARE OFF A 1963 GALE BUCCANEER 5HP OUTBOARD, IT DID HAVE SPARK PRIOR TO TEARDOWN, BUT DID NOT HEAR IT RUN.

I CAN ONLY GUARANTEE FITMENT OF THIS YEAR AND MODEL, 

NO RETURNS OFFERED

BUYER ASSUMES ALL LIABILITY FOR PURCHASE, FITMENT AND INSTALLATION OF PART

THANKS FOR LOOKING

GOD BLESS/JOHN 3:16
