Trolling Motor Adapter for Underwater Lights
The Trolling Motor Adapter for Underwater Lights is a fast, low-profile mounting solution that lets you attach underwater lights directly to your trolling motor—turning nearly any boat into a capable flounder gigging, bowfishing, night fishing, shrimping, or bully netting setup in minutes.
Designed for quick installation and removal, this adapter clamps securely to your trolling motor shaft using hand-tightened wing nuts and stays locked in place even in rough water. Its adjustable design fits most trolling motor shafts and supports 1 to 5 underwater lights, delivering focused illumination exactly where you need it—right below the motor.
- Quick on / quick off — mount in minutes, remove just as fast.
- Low profile & locked in — stays put even when conditions get rough.
- Forward-facing illumination — lights where you’re going, not behind you.
- Expandable — run 1 light or build up to 5 depending on your water and style.
