Extreme Beam FAQS, Installation & Specs

Easy 5-Step Installation For Fiberglass Hulls
1. Verify that the hull thickness does not exceed 3” or 80mm then select the location choice on your boat approximately 12” or 250mm below the water line. Drill using a pilot bit first to ensure there are no internal obstacles.
2. Loosen the cable connector at the rear of the cap, then remove the rear cap counter clockwise and place light and cap in a safe place until fixture is installed. Using a holesaw, cut out a 4.50” or 115mm diameter hole.
3. Clean hole thoroughly using 3M adhesive remover or a similar alcohol-based agent. Be sure to seal the core, if needed, with marine epoxy or 3M 5200.
4. Install the fixture using 3M 5200 or 4200 Fast Cure Silicon, just as you would with any other thru hull, then hand tighten internal locking ring. Once the ring has been tightened, lock the 4 locking bolts firmly against the hull. Next clean all excess 5200 from the surrounding area with 3M adhesive remover or a similar alcohol-based substance.
5. Re-connect cable connector, then hand tighten cap clockwise. Be sure to leave sufficient cable length for bulb changes and service ( + 2-3 feet). Connect bonding strap.

FAQs
Why should I put an underwater light on my vessel? Underwater lights are a great addition to your vessel for many reasons. They enhance the overall appearance of your yacht and allow you to enjoy the beauties of the ocean even after the sun goes down. Underwater lights allow you to attract fish (a favorite tool of fisherman) and illuminate the natural wonders that lie beneath the water's surface.

How far below the water line should an underwater light be installed? Underwater lights should be installed approximately 12" below the water line.
Should I put more than 1 Underwater Light on my vessel? Even 1 underwater light is a great enhancement to your vessel and your overall yachting experience. Depending on your budget, however, three or more lights will work together to create the optimal effect.
