In the event that the engine is accidentally submerged in water. Take it
out of the water and wash it with fresh water to remove all traces of salt
and dirt. Remove the spark plugs and drain the engine completely of water.
turn the flywheel several times using the starter rope. Drain the fuel line
and carburetor. Inject copious amounts of engine oil for storage or fogging
oil into the engine through the spark plug holes and air silencer. Turn the
flywheel several times with the starter rope while injecting the oil to make
sure the oil is evenly distributed. Spray the entire engine with silicone
spray to prevent rusting, and short circuiting. It may now be possible to
start the engine. However all the electrical components and carburetor will
soon deteriorate and become in operative. Be sure to have the engine
overhauled by your dealer as soon as possible.

If it is not possible to start the motor or have it serviced promptly
resubmerge it immediately in fresh water and avoid exposing it to air.

This is when the wife freaked out when both engines were in the two bath
tubs for 3 weeks.

Hi,

Need any help / advice on this subject. My boat, along with my 115HP
Merc outboard was completely submerged as a result of hurricane
Isabelle. It was underwater for about 18 hours, with battery
attached, in brackish water.

It's had time to dry now - should I just try to start it and see what
happens? Or would that likely risk further possible damage? Any
suggestions?

Thanks so much,
Brian Klug
