Operation
The digital switch that operates the courtesy and storage light can 
be found on the touchscreen dash on the lighting tab. It can be 
toggled ON and OFF by taping the Courtesy/Storage Light button.
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 LEDs, which rarely burn out, it is possible. Take the boat to an 
authorized MasterCraft dealer to have the bulb replaced.
UNDERWATER LIGHTS
Models
All models, as an option.
Purpose
Underwater lights provide a significant improvement in visual 
illumination of the water beneath swim platforms and in the area 
surrounding the boat stern. In shallow water, this can be especially 
useful in determining safer operations.
Location
Located on the transom below the waterline under the swim platform.
Operation
The digital switch that operates the underwater lights can be found 
on the touchscreen dash on the lighting tab. Toggle the lights ON 
and OFF by taping the Underwater button. The lights will come ON 
and the screen will highlight the lights on the screen. 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 eect of the water to avoid prematurely 
burning out the bulbs. Underwater lights may have thermal protec-
tion circuitry that will turn the light o when reaching high tempera-
tures.  Allow lights to cool in water in order to turn back on.
