Post Submersion

Whenever possible after submersion in sea water, upon completion of operational period, wash
entire engine and powerhead with fresh water to remove salt deposits, especially under the
Recoil Starter and Flywheel where the accumulation of deposits will build up. Raider recommends
that your organization use Salt-Away when conducting post submersion maintenance. Salt-Away
is a water-based, non-hazardous, biodegradable solution and contains properties that dissolve,
release and remove salt crystals from any surface.
Works to protect against salt corrosion and
reduces costly unforeseen maintenance actions caused by salt. Salt-Away breaks apart and
removes salt accumulation with repeated use.

After submersion and operation, if the Raider cannot be immediately serviced, keep it submersed
or re-submerge the motor until time is sufficient that it may be serviced. Avoid prolonged
exposure to the atmosphere. If possible, submerge in fresh water but even prolonged salt water
submersion is preferable over exposure of an unserviced motor to the atmosphere. When
operations are concluded, simply recover the motor and Dewater following the Dewatering
Procedures and proceed with service.

After submersion period it is critical that the motor must be run at operating temperature for no
less than 30-minutes to ensure all water is removed from the head. Raider recommends that your
organization use STA-BIL 360 Marine treated fuel during this run period. STA-BIL 360 Marine
provides enhanced water removal properties to prevent fuel system corrosion. Engineered
specially for the harsh coastal climates, prevents corrosion, cleans the fuel system and prevents
the buildup of unwanted gum and varnish; mitigating the adverse effects of submerging your
Raider 50 HP.

After the 30-minute run period, disconnect the fuel supply with the motor running and let the
motor run itself dry.

Using LP air, if available remove excess water from the surfaces of the powerhead. Force air under
the recoil starter and flywheel. If LP air is not available, use shop towels or rags to remove excess
water.

Spray the entire power head with a liberal coat of Anti-Corrosion Spray penetrate/lubricant or
equivalent. Raider recommends that your organization use Corrosion Zero, a special corrosion
preventative compound that prevents deterioration and contamination of all surfaces of
electronic equipment and mechanical close-tolerance components. This corrosion inhibitor
contains extremely long-lasting, specially formulated and proprietary anti-corrosive inhibitors
that provide a superior lubrication coefficient. Corrosion Zero film remains flexible and will not
crack when the treated material is subject to vibration and/or thermal expansion or contraction.
It is the flexibility of the film that makes Corrosion Zero extremely effective against fretting
corrosion. Also, because the film is not rigid, the film tends to be "self-healing" and will fill
scratches that are caused by the mating and/or unmating of close tolerance parts.

Leave the upper cover off, when possible to allow the power head and other components to air
dry.

Unplug or remove battery – place on battery tender to maintain charge.
