O–Ring Cylinder Head

2001 MY

The cylinder head O-ring seals have a new profile/ design. The purpose of this

new design is to fill as much of the O-ring groove as possible. This pre-vents

oil from accumulating around the O-ring and breaking down the O-ring

material.

NOTE: Model Year 2000 – Cylinder head o-rings are oval shaped and are not

directional in their installation. O-rings should not be damaged or twisted.

Replace as required.

Model Year 2001 – Cylinder head o-rings are directional in their installation.

The grooved side faces the cylinder block. The pointed side faces into the

cylinder head. Failure to install the o-rings correctly may result in cylinder

head leakage. O-rings should not be damaged or twisted. Replace as

required. The 2001 style o-rings supercede and backfit to 2000 Model Year

outboards.

Also see “Service Bulletin 2002-13” for more information.
