CLEANING AND MAINTENANCE-8
If a marine railway or platform hoist is being used,
locate and adjust the blocking to distribute the weight
over several areas. The weight borne by the keel
must not be so great as to cause crushing or distor-
tion of the member.
When lifting the yacht, keep the bow higher than
the stern so the engine and generator (if so equipped)
exhaust lines can drain. This will prevent water from
fl owing forward through the manifold and into the
engine itself, where it may become trapped.
Always keep the bow higher than the stern every
time the yacht is lifted. DO NOT lift the stern
higher than the bow at any time as this may
cause water to enter the engines. Engine failure
is possible if water enters the engine cylinders.
The water can cause “hydrostatic lock” and bend
the piston rods. “Hydrostatic lock” is a situation
where the piston cannot travel to its full upward
position due to the presence of a liquid above
the piston and extreme pressure is forced down-
ward as the piston moves upward. Even a small
quantity of water can cause rust or other internal
engine damage.
NOTE: Silverton recommends an optional storage
cradle with the purchase of your yacht. The cradle
is factory made to conform to the bottom of your
yacht for safe storage and minimizes the risk of hull
distortion.
