Upgrade your helm setup with the Mercury Outboard Side Mount Control with Trim 15FT (8M0178539). Designed for compatible Mercury outboard applications, this genuine Mercury Marine control combines throttle, shift and power trim functions in one convenient side-mounted unit.
Featuring a 15-foot configuration, this control provides flexibility when routing the system between the helm and engine. Therefore, it makes a practical choice for new installations, repowers and replacement applications.
Throttle, Shift and Trim Control
The Mercury Side Mount Control gives the operator convenient access to essential engine functions from one location. The control lever manages throttle and shifting, while the integrated trim function allows you to adjust the outboard’s trim position.
As a result, you can make quick adjustments without moving between separate controls. This helps create a simple and user-friendly helm setup.
Integrated Power Trim Function
Correct engine trim can help improve your boat’s running attitude, handling and performance. The integrated trim control allows the operator to raise or lower a compatible Mercury outboard directly from the remote control.
This convenient design keeps the trim function within easy reach while cruising, manoeuvring or adjusting the boat for changing conditions.
Practical Side-Mount Design
The side-mounted configuration works well for many boat layouts, particularly where console space is limited. Furthermore, the 15FT length offers flexibility when routing the control system through the vessel.
Its compact layout helps maintain a clean and organised helm while keeping important controls easily accessible.
