Periodic Maintenance Procedures
•
Apply molybdenum disulfide oil to the valve lifters and ap-
ply engine oil to the shims, and install them.
•
Install the camshafts. Be sure to install the camshafts
properly (see Engine Top End chapter).
•
Remeasure any valve clearance that was adjusted.
•
Readjust if necessary.
CAUTION
Do not put shim stock under the shim. This may
cause the shim to pop out at high rpm, causing ex-
tensive engine damage.
Do not grind the shim. This may cause it to fracture,
causing extensive engine damage.
Engine Mounting Bolts Inspection and Tightness

If there are loose bolts, remove the bolts.
•
Apply a non-permanent locking agent to the engine
mounting bolts and tighten them.

Cooling and Bilge Systems
Cooling System Flushing
To prevent sand or salt deposits from accumulating in the
cooling system, it must be flushed occasionally. Flush the
system according to the Periodic Maintenance Chart, after
each use in salt water, or whenever there is reduced water
flow from the bypass outlet on the right side of the hull.
