Mercury – Joystick Assembly for Multi-Engine JPO | Control System | 8M0178012

Overview
This joystick assembly is the core control piece used in multi-engine Joystick Piloting setups from mid-2016 onward. It gives the helm a smooth, steady feel, letting you make small directional changes without overcorrecting. The movement feels natural—easy to nudge, but firm enough that you won’t bump it by accident. It drops in as a direct service replacement for boats already running Mercury’s JPO system.

Key Features
 • Multi-Engine Joystick Control – Designed for boats using full Joystick Piloting.
 • Smooth Low-Speed Handling – Helps with tight docks, fuel piers, and narrow channels.
 • Direct Replacement Component – Fits JPO systems from mid-2016 and newer.
 • Integrated Movement Sensors – Sends clean signals for shift, throttle, and steering commands.
 • OEM Fitment – Matches factory JPO installations without modification.

Engine & Boat Compatibility
 • Joystick Piloting for Outboards
 • Joystick Piloting for Inboards/Sterndrives
 • Multi-engine DTS
 • Mid-2016 and newer JPO systems

Performance & Practical Benefits
On the water, the joystick gives you calm, predictable control when you’re working a bigger boat into tight spots. Each movement translates smoothly, so the boat reacts without jerking or lagging. It makes sideways moves, pivots, and slow approaches feel more controlled, especially on windy days. The feel stays consistent, which helps you build confidence after just a few uses.

Why Buy OEM
OEM joystick components keep the whole JPO network in sync—throttle, shift, steering, and sensors all communicate cleanly. Mercury’s calibration keeps the response steady over time, so the joystick feels the same season after season. It’s the safest choice for replacing a worn or damaged unit.

FAQ
Q1: How do I know if my current joystick needs replacing?
A: If movements feel jumpy, delayed, or the boat stops responding cleanly, the joystick is often the first place to check.

Q2: Does this need setup after installation?
A: Yes—JPO systems require a quick calibration so everything syncs correctly.

Q3: Is it okay for saltwater use?
A: Yes, just keep up with normal helm cleaning and rinse after heavy spray.

Q4: What should I check before installing?
A: Make sure the existing JPO system is mid-2016 or newer so the harness and mounting match up.

Q5: What if the joystick moves freely but the boat doesn’t react?
A: That’s usually a calibration or network issue, not the joystick hardware itself.
