completely drained. Waterproof tags shall be attached to all broken connections, closed or open valves, fill-
ing connections, and to the helm or tiller to indicate the necessity for reconnection or replacement of plugs
before filling tanks. Secure openings to fresh water tanks after draining to prevent contamination.
b. The engine cooling and exhaust system has been drained and the engine and accessory equipment have been
preserved. Refer to
paragraphs 583-9.2.2 through 583-9.2.2.1 for procedures on preserving engines.
c. All exterior surfaces; cabins, lockers, holds and bilges have been cleaned and limber holes and scuppers are
unobstructed.
d. All fittings, piping, shafting, propellers, and bearings have been preserved with a coating of MIL-PRF-16173E,
water displacing soft film (NSN 8030-00-244-1296).
e. All fresh water has been removed from piping, freshwater tanks, engines, pumps, exhausts, and bilges. All
drain plugs have been removed and attached in a packet to the steering wheel or tiller. The boat is properly
trimmed on it’s cradle/trailer to facilitate drainage.
f. Check to be sure batteries have been removed after preservation is completed.
g. Propellers less than 24 inches in diameter, and those, whose blades protrude beyond the keel line, are removed
and stored within the boat. Shaft keys, propeller nuts, cotter pins, and other parts shall be replaced on shaft
and secured as necessary. Do not apply contact preservative to rubber. Propellers larger than 24 inches in
diameter and not protruding beyond keel line need not be removed from the shafts.
h. The hull registry number is either molded on the transom or otherwise legibly marked on the hull of the boat.
If a hull registry number, which is only painted on the hull, is removed during repairs, it shall be replaced
immediately after repairs to that area are completed.
i. All boats that PEO SHIPS PMS325 has declared excess or that PEO SHIPS PMS325 has advised are beyond
economical repair, shall be plainly marked with the letter D either on the bow or on the transom. The letter
shall be approximately 12 inches high and made with yellow paint.
j. All dunnage, lifejackets, and rope shall be removed. All canopies shall be removed, dried and stored sepa-
rately in a dry secure location on the boat or packaged in water resistance packaging and stored in areas
exposed to the weather on the boat.

583-9.2.2 BOAT ENGINE, REVERSE GEAR, AND PROPULSION UNIT PRESERVATION. The instructions
for preservation of engine, reverse gear, and propulsion unit shall be accomplished in accordance with PMS pro-
cedures and the manufacturer’s recommendations. Manufacturer’s recommendations are found in the
Commercial-Off-the Shelf manuals and data provided with the boat. Additional guidance can be found in appro-
priate MIP. Preservation methods shall displace dirt, water, and oil, and leave a continuous protective film on sur-
faces. Excess preservative is to be drained off to prevent the formation of stagnant pools that may, with age, tend
to solidify and complicate putting an engine back into service.
583-9.2.2.1 Motoring Engine. If it is feasible to turn the engine over by motoring, the following steps are to be
followed:
a. Thoroughly drain the engine and reduction gear of all water, lubricating oil, and fuel oil. Use forced air to
blow-dry seawater and freshwater systems. In addition, completely drain and air-dry the exhaust system.
b. Remove engine and reduction gear oil cartridge and spin-off type filter elements and clean the interiors of all
strainer and filter housings. Install new oil filter elements.
