Quad tower speakers, subwoofer, auxiliary battery, four tower lights, eight courtesy lights and a custom powdercoated tower are just a few of the upgrades on this twin engine jetboat.

First we removed the brushed aluminum tower. We welded four aluminum halogen light brackets directly to the tower. Then we had the tower powdercoated in a high gloss black to coincide with the black hull.

Four black halogen lights are integrated into the tower with a minimum of mass and exposing wiring.
Four individual black bullet-shaped aluminum pods adorn the tower. The outside position alleviates clearance issues with the biminy top and also keeps the profile low for easy dry storage access. 

The 10-inch subwoofer enclosure is water-resistant due to a triple coating of fiberglass resin over a non-water-soluble lumber product. The enclosure is wrapped in marine grade carpet and elevated off the soul of the locker to ensure its integrity is maintained permanently. Three aluminum brackets secure the enclosure.

A vent under the passenger side dash allows the bass radiation from the concealed subwoofer to flow freely.

We constructed a birch amplifier panel clad in matching marine carpet. While one amplifier drives the subwoofer the other drives the four tower speakers.

A dual battery switch was added along with a group 27 deep cycle auxiliary battery. The second battery was mounted in the opposite transom locker.
Concealed in the glove box and next to the factory CD player a switch turns on and off the tower speakers.

A marine switch protected by a watertight boot is mounted in the driver’s combing pocket. This switch controls relays that handle the current drawn by the four tower-mounted halogen lamps.

Red LED courtesy lights illuminate the dual drink holders in each of the cockpit combing pockets.
Red LED step lights cast light over the drink holders on each side of the bow. With their small size the lighting group is easily overlooked but their effect is big!
Red LED step lights on each side at the very back of the cockpit.
Red LED step lights far forward in the cockpit.

Eight red LED clusters illuminate the drink holders plus outline the deck for safety at night. Red was selected to tie into the red graphic accents in the boat’s hull.

For contrast here are several other Yamaha wakeboard boats with different color tower schemes.
