INSTALLATION INSTRUCTIONS
Please read completely before installation:
- Choose mounting location – The lights require water cooling and should be installed on a flat surface area that is below the water line. Also consider the area inside the boat where the wire will enter and make sure it will be accessible to retrieve the wire. It is NOT recommended to mount the lights on hull running surfaces.
- The template below can be used for finding an appropriate mounting location. Verify that the template matches the mounting holes on the light if using this as a drill template. Make sure you are drilling into a place where you can get to the hole from inside the boat in order to feed wire. Mark center drill location with pencil.
- Drill a 5/8″ diameter hole for the cable in the center hole location only (shown on template).
- If mounting to an aluminum hull you will need to purchase part number: SCM-GASKET-SC3SM or SCM-GASKET-SC3SM-BR for galvanic isolation to prevent corrosion.
- Feed the cable through the hull into the boat.
- With the light against the hull in the location to be mounted, use the actual mounting holes of the light to mark one mounting hole. Drill that hole with an appropriately sized drill (9/64 is typical for #8 screws). Be sure the drill is not over sized or undersized. An undersized hole can cause the screws to break, oversize the hole and the hole will strip. With the light in place thread a screw into the hole. Perform same steps for remaining holes.
- Place a sufficient amount of marine sealant on the hull around all holes to seal them against the light’s base plate.
- Fill the screw holes with sealant.
- Use provided screws to mount light to the hull. If alternate screws are used they must be silicon bronze. After mounting wipe off any excess marine sealant around the light. Gently remove any spots with denatured alcohol on a lint free rag or cloth.
CONNECTIONS

CARE AND MAINTENANCE
Clean your Shadow-CasterTM Marine LED lights frequently with a soft bristle
brush. We recommend that installed ShadowCasterTM Marine LED lights be cleaned
every 2 weeks for “live in water” boats, and rinsed every time the boat is
pulled out of the water to prevent marine growth buildup and bio-fouling.
