Sports Tow
A water sports tow is located on Power Tower models. Always appoint
a person to keep their "eye out" for the tow line when the vessel is
running to prevent the line from being tangled in an object such as
the propellers.
Optional hard top models at the time of manual printing do not offer
a water tow option.
Never use the sports tow for lifting the boat. Damage to the sports
tow and boat will occur.
SureShade
SureShade
If installed, the hard top features a center soft sun roof. A built-in
SureShade is optional. The hard top may also include 2 speakers and a
a LED accent lighting system. A switch controls the shade operation.
N OTT: The SureShade is to be used only when the boat
is moored or not making headway. Do not use the
component when the boat is in motion.
