Operating in Freezing Temperatures
When using your outboard or having your outboard moored in freezing or near
freezing temperatures, keep the outboard tilted down at all times so the
gearcase is submerged. This prevents the trapped water in the gearcase from
freezing and causing possible damage to the water pump and other
components.
