WARNING
This component or assembly weighs greater than 23
kg [50 lb]. To prevent serious personal injury, be sure
to have assistance or use appropriate lifting
equipment to lift this component or assembly.
The engine needs to be supported before removing the
isolators. The amount of space available will determine
the best method for this support.
Remove the top nut from the isolator's adjusting stud.
Remove the bolts or capscrews retaining the isolator
base.
Raise the engine if necessary to facilitate the removal of
the isolator.
Make sure that any equipment used for hoisting of jacking
the engine is capable of handling the weight of the engine
and marine gear. Any engine component used for
attaching or support such as the lifting brackets or engine
supports must be correct for the engine. Reference the
appropriate manual for General Engine information in
Section V for the engine weight.
Remove the isolator.
If reusing the isolator, mark the position of the isolator
relative to the engine to make sure of installation in the
same location.
If replacing the worn or damaged isolator with a new
isolator, measure the height of the adjusting nut on the
stud to assist in setting the new isolator adjusting nut
height.
Inspect for Reuse
Inspect the vessel stringers or engine bed to make sure
they have not been damaged and that they can continue
to support the weight of the engine. This is especially true
of stringers constructed of wood, wood core, or hollow
fiberglass.
Inspect the mounting holes in the stringers or the engine
bed for damage. If the stringers, engine bed, or mounting
holes need to be repaired, contact an OEM qualified
repair location.
