Overview
This flush-mount trim pad gives triple-engine DTS setups an easy, clean way to adjust trim right from the helm. It sits low in the dash, so it doesn’t add clutter or get in the way when you’re running the boat.

On a triple-engine rig, having trim controls laid out neatly at the helm makes everyday driving a lot more comfortable.

Performance & Practical Benefits
Having trim controls built into the dash keeps everything within easy reach, which really helps when the water changes quickly or you’re dialing in the running angle. Each engine can be trimmed individually without shifting around the helm or juggling extra switches. The flush pad keeps the dash clean and uncluttered, which is especially helpful on boats with a lot going on at the helm.

Why Buy OEM
OEM trim pads fit the DTS harness exactly and hold up well in heat, vibration, and spray. The buttons feel consistent, and you don’t deal with the odd behavior or loose connections that show up with non-OEM options. It’s built to last and to feel the same season after season.
