If the RPM reading is reading correctly and the engine throttle settings are correct, the tachometer is
operating properly. If the tachometer is not reading correctly, refer to the manual provided by the
manufacturer of the gauge (included in your owner’s package).
Speedometer - To ensure that the speedometer (Speedo) is working properly, get the boat on a planing
speed and check to see if the gauge is reading at the approximate running speed at which the boat is
traveling.
Note: The speed-reading on the Speedo may vary a few mph from the actual speed that
the boat is traveling. Either a GPS or a radar gun can check the running speed.
Fuel - The fuel gauge reads the amount of fuel remaining in the tank. To check the fuel gauge, place a
known amount of fuel into the fuel fill and fill the tank. Turn the ignition key on and the fuel gauge should
read the approximate amount of fuel in the tank.
For example: If the fuel tank holds 125 gallons of fuel and you pumped 31 - 32 gallons of
fuel into the tank, the fuel gauge should read approximately ¼ of a tank. This ensures
that the fuel gauge and the fuel sender are working properly.
If the fuel gauge is not reading correctly, we recommend that you have the fuel sender checked by a
qualified professional before considering changing out the gauge. For more information, please refer to
the Fuel/Oil Systems section of this manual.
Trim - To ensure the trim gauge/indicator is working properly, start by making sure the engine is trimmed
all the way down. Locate the trim gauge on the instrument panel and check to see if the level on the trim
gauge is in the full down position. As you trim the engine up, watch the trim gauge and ensure that it
coincides with the actual trim of the engine. When finished trimming the engine all the way up, the level
on the trim gauge should read in the full up position.
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 14½ volts. This
reading ensures that the charging system and the volt gauge are working properly.
For specific information related to your gauges, refer to the materials in your owner’s package that was
provided by the gauge manufacturer.

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.
