2016 OWNERS MANUAL / 0241
Also note that the underwater lights should never be operated
unless the boat is in the water. Even though these are LED lights,
they generate some heat and require the cooling effect of the water
to avoid premature burn-out of the bulbs. Underwater lights may
have thermal protection circuitry that will turn the light off when
reaching high temperatures. Allow lights to cool in water in order to
turn back on.
Troubleshooting
If lights do not operate, check the main circuit breaker panel to
determine if a circuit may have tripped. Reset the circuit; if it
continues to trip, take the boat to an authorized MasterCraft dealer.
If the circuit breaker has not tripped, the bulb may have burned out.
Although the lights are LED, which rarely burn out, it is possible.
Take the boat to an authorized MasterCraft dealer to have the bulb
replaced.
