IMPORTANT: If boat is operated in freezing temperatures, ensure

The engine compartment in your boat is a natural place for water to
collect. For this reason, boats are normally equipped with a drain
plug and/or a bilge pump. It is very important to check these items
on a regular basis to ensure that the water level does not rise to
come in contact with your power package. Engine components will
be damaged if submerged. Damage caused by submersion is not
covered by the Mercury Racing Limited Warranty.

In any of the situations described in the preceding notice, water
entering the engine could cause severe damage to internal parts.
