Dewater Procedure

ture. In other than mission situations, run engine under normal operating conditions for 15 to 40

v. Post Submersion Procedure
After your mission, the Raider must be prepared to be returned to nonuse or prepared for
your next mission.
If the RAIDER is re-submersed after your mission and it cannot be serviced, keep it submersed
to avoid prolonged exposure to the atmosphere, until it can be serviced. If the Raider is brought
on deck and it can’t be operated or serviced, keep it submerse in fresh water, but get it prepared
for your next mission as soon as possible.
If the RAIDER can be operated on deck, dewater the engine following the procedures in
De-
water Procedure
; operate the engine for approximately five minutes at full operating tempera-
ture with fresh water. Remove the upper cover to allow the powerhead and other components to
air dry. Whenever possible after use or submersion in sea water, wash entire engine with fresh
water to remove salt deposits and wipe down with a dry cloth. Spray the entire powerhead with
an Anti-Corrosion Spray/penetrant/lubricant or equivalent. Follow this procedure to prepare the
Raider for your next mission.
