Outboard motors operating under any of
these above conditions require more frequent
maintenance. Yamaha recommends that you
do this service twice as often as specified in
the maintenance chart. For example, if a par-
ticular service should be done at 50 hours, do
it instead at 25 hours. This will help prevent
more rapid deterioration of engine compo-
nents.
