Propeller Shaft
Clean the exposed surfaces of the propeller
shaft with dry cleaning solvent, Stoddard
Solvent or equivalent; then follow with an
application of finger print neutralizer, and
dry. Coat the surfaces with soft film
corrosion preventive compound. After the
compound has set, protect the surfaces by
wrapping with a suitable acid-free waxed
paper and secure with tape. Install a
propeller thread protector. If the hoisting
eye is installed, which will be needed to
place the engine in the shipping container,
installation of the shipping cap should be
delayed until after the engine is secured to
the base of the packing box.

Accessories
Drain the fuel from the engine driven fuel
pump and the oil from the propeller
governor and flush with corrosion preventive
mixture while rotating the crankshaft to
ensure complete preservation of all internal
parts. All accessories not attached to the
engine should be treated for proper storage
preparation. Drain the excess oil and wrap
these accessories in acid-free waxed paper.

stacks and then seal with moisture resistant
sealing tape; or install exhaust port covers
