1. Choose a location on the transom 6 to 12 inches beneath the waterline. The mounting surfaces should be flat, clean, dry, and free of existing hardware or holes. Check inside the hull for wiring or obstructions.
2. Before mounting, ensure that the light will not interfere with the operation of engines, trim tabs, rudders, etc. Clean the gelcoat or remove any bottom paint from the gelcoat surface. Mark the light center and drill the appropriate hole (0.5"). 
3. Spread a generous bead of sealant (3M4200 or equivalent) around the inside surface of the light bezel, the screw holes, and the wire stem up to the exposed wire.
4. Feed the light housing through the hole and orientate using the logo on the reflector. Fasten in place with tape.
5. On the inside of the hull, apply a generous bead of sealant (M4200 or equivalent) to the wire through-hull hole before installation of the Light.
6. On the exterior, feed the isolating washers over the screws and tighten the screws hand-tight with a screwdriver (do not use power tools as you may snap the bronze screws).
7. You should see sealant expelled from around the light housing to ensure adequate bond. Wipe off any access sealant.

Wiring recommendations: Use ABYC standards to calculate wire size based on the length of the run. 

TIP: To minimize electrical noise and interference, running the positive (red) power and ground (black) return together for as much of the wire run as possible, ideally inside a jacketed cable, is recommended. Avoid loops and coils of the wiring.

• Ensure that the circuit you are connecting to has no power. You should turn off your house battery and test to ensure the circuit is not energized by using a multimeter before continuing.
• Run a marine grade 2 conductor wire from the light to your switch and power source. The red wire will connect to constant power after the house power kill switch, the black to common ground, and the orange wire to the normally open side of a switch. You should install a 1A fuse on the red wire on a 12vDC system (1A @ 24vDC).  View wire gauge reference chart HERE.
• Connect the wires from the light to the new wire run and follow ABYC standards. Ensure that the wires are crimped correctly, and use a heat gun on the heat shrink of the butt splice connectors. 
• Turn on house power and test the new underwater light.

Note: Only the SeaBlaze Mini Spectrum light is compatible with the Poco system (PLI-enabled). Single-color SeaBlaze Mini lights are not compatible with Poco.
