Volts
To system check the volt gauge, turn the ignition key on and turn on the engine. With the engine running,
check the reading on the volt gauge. It should be reading between 12 and 14.5 volts. This reading
ensures that the charging system and the volt gauge are working properly.
Head Waste System
WHAT IS THE LAW?
Congress enacted the Clean Water Act of 1972 (amended in 1987). This law
addresses a wide spectrum of water pollution problems, including marine sewage from boats in navigable
U.S. waters including coastal waters up to three miles offshore. The law further provides for "no
discharge" by boats operated in enclosed lakes and reservoirs or in rivers not capable of interstate
navigation. States may apply to the EPA to have certain other waters declared "no discharge zones" if
discharge of treated sewage would be harmful. In short, boats with installed toilets must have an
operable Coast Guard approved Marine Sanitation Device (MSD) designed to either hold sewage for
pump out ashore or for discharge in the ocean beyond the three mile limit, or to treat the sewage to
Federal standards prior to discharge.
All boats built since 1977 with installed toilets must have an operable approved type I, II or III MSD.
Since 1980, all boats (including those built before 1977) with installed toilets must have an operable MSD.
Both the U.S. Coast Guard and the Natural Resources Police can enforce MSD requirements.
Check with your local authorities, Coast Guard, local marina or your dealer for the rules and/or laws that
may apply specifically in your area.
Console w/Enclosed Head (Porta-Potti)
A porta-potti with a 2.8-gallon holding tank comes standard with the 21 Sport. To operate the porta-potti
system:
•
Set the portable toilet on its front side so the cap on the holding tank is in a vertical
position. Remove the cap and add SeaLand brand holding tank deodorant following the
instructions on the deodorant container. Replace the cap firmly.
•
Before using: Set the portable toilet in the upright position and remove the cap located
on the right, rear side of the fresh water tank. Fill with fresh water just below the neck of
the fresh water inlet. Depress the bellows pump to add water to the bowl.
•
After using: To flush, open the slide valve by pulling out the handle and press the
bellows pump one or more times. After flushing, close the slide valve by pushing
the
handle.
•
Caution: Never add holding tank deodorant to the waste holding tank by pouring directly
into the toilet bowl.
Before operating the porta-potti head system, refer to the manual in your owner's packet supplied by the
porta-potti manufacturer for specific operating instructions.
Sea Water System
Baitwell / Washdown Pump
The baitwell switch at the helm controls the baitwell/washdown pump. The pump and seacock are
mounted in the bilge and are accessible through the bilge hatch in the motor well at the transom. Raw
water for the baitwell tub and raw water washdown system comes through the seacock, to the pump and
then to the baitwell tub and/or raw water washdown outlet. Before turning the pump on from the helm,
check to be sure that the seacock is open. The seacock is wide open when the yellow seacock lever is
vertical. When the yellow seacock lever is horizontal, the seacock is closed. The seacock should remain
closed when the pump is not in use.
