GENERAL INFORMATION
SERVICE MANUAL NUMBER 25
IMPORTANT: If antifouling protection is required, Tri-Butyl-Tin-Adipate (TBTA) base
antifouling paints are recommended on Mercury MerCruiser boating applications. In
areas where Tri-Butyl-Tin-Adipate base paints are prohibited by law, copper base
paints can be used on boat hull and boat transom. Corrosion damage that results
from the improper application of antifouling paint will not be covered by the limited
warranty. Observe the following:
Avoid an electrical interconnection between the Mercury MerCruiser Product,
Anodic Blocks, or MerCathode System and the paint by allowing a minimum of 1-1/2
in. (40mm) UNPAINTED area on transom of the boat around these items.

Weight Distribution
Weight distribution is extremely important; it affects a boat’s running angle or attitude. For
best top speed, all movable weight - cargo and passengers - should be as far aft as possible
to allow the bow to come up to a more efficient angle (3 to 5 degrees). On the negative side
of this approach is the problem that, as weight is moved aft, some boats will begin an
unacceptable porpoise.
Secondly, as weight is moved aft, getting on plane becomes more difficult.
Finally, the ride in choppy water becomes more uncomfortable as the weight goes aft. With
these factors in mind, each boater should seek out what weight locations best suit his/her
needs.
Weight and passenger loading placed well forward increases the “wetted area” of the boat
bottom and, in some cases, virtually destroys the good performance and handling
characteristics of the boat. Operation in this configuration can produce an extremely wet
ride, from wind-blown spray, and could even be unsafe in certain weather conditions or
where bow steering may occur.
Weight distribution is not confined strictly to fore and aft locations, but also applies to lateral
weight distribution. Uneven weight concentration to port or starboard of the longitudinal
centerline can produce a severe listing attitude that can adversely affect the boat’s
performance, handling ability and riding comfort. In extreme rough water conditions, the
safety of the boat and passengers may be in jeopardy.
