material being used. The slot in front engine mounts should face forward. Do not install
fasteners at an angle.
Serviceability
All engines require maintenance and some will require service repair within the life of the
product. Considering serviceability when designing the engine compartment could have a
major impact on customer and dealer satisfaction.
In addition to customer and dealer satisfaction, consider the implications of serviceability
with respect to our warranty policy.
The Mercury MerCruiser warranty policy states, in
part, that reasonable access must be provided to the product for warranty service.
Refer to the warranty policy in the appropriate Operation, Maintenance, and Warranty
Manuals . It states that removal or replacement of the boat partitions or material because
of boat design for necessary access to the product is not covered. Consider serviceability
when designing the boat and engine compartment to avoid these types of issues.
Consider all engines options used in a boat when designing the engine compartment. The
engine size differences between some of the models as well as differences in service point
locations may have a major effect on serviceability.
