Submerged Motor - Honda BF8A Owner's Manual

TAKING CARE OF UNEXPECTED PROBLEMS
SUBMERGED MOTOR
A submerged motor must be serviced immediately after it is recovered from
the water in order to minimize corrosion.
If there is a Honda marine dealership nearby, take the motor immediately to
the dealer. If you are far from a dealership, proceed as follows:
1.
2.
3.
4.
Remove the engine cover, and rinse the motor with fresh water to remove
salt water, sand, mud, etc.
Loosen the carburetor drain screw (p. 61) drain the contents of the
carburetor into a suitable container, then tighten the drain screw.
Change the engine oil (p. 49). If there was water in the engine crankcase,
or the used engine oil showed signs of water contaminator-r, then a second
engine oil change should be performed after running the engine for l/2
hour.
Remove the spark plugs. Disengage the emergency engine stop switch clip
from the engine stop switch and pull the recoil starter several times to
completely expel water from the cylinders.

When cranking the engine with an open ignition circuit (spark plugs
removed from the ignition circuit), disengage the emergency engine stop
switch clip from the engine stop switch to prevent electrical damage to the
ignition system.
l
If the engine was running when it submerged, there may be mechanical
damage, such as bent connecting rods. If the engine binds when cranked,
do not attempt to run the engine until it has been repaired.
