Mercury – Flush Mount Trim Pad (Quad Engine) | Helm Trim Control | 87-879303A04

Overview
This flush-mount trim pad gives quad-engine DTS setups an easy, clean way to manage trim for all four engines right from the helm. The pad sits low in the dash, so it doesn’t crowd your controls or get in the way when you’re running the boat. Each button has a comfortable feel, making it simple to make quick trim tweaks as conditions change. On a quad-engine rig, having trim control laid out neatly in one spot makes the whole boat feel easier to manage.

Performance & Practical Benefits
Trim adjustments get a lot easier when everything sits right in the dash. Each engine can be trimmed independently without fumbling for extra switches or shifting your grip around the helm. The pad keeps the dash tidy and helps you stay focused when balancing the boat on plane or running in rough water. On a quad setup, that quick access makes a noticeable difference.

Why Buy OEM
OEM pads plug straight into the DTS harness and handle vibration, spray, and sun without wearing out early. The buttons feel consistent, the fit stays tight, and the wiring behaves the way Mercury designed it to. It’s a reliable, no-drama piece of gear.

FAQ

Q3: How does it handle saltwater?
A: Very well. Just rinse the area occasionally and keep the connector clean.
