Mercury – JPI Single Thruster Kit SF2 | Control System | 98-8M0171473

Overview
This kit gives a single-engine inboard setup everything it needs to run a Side Power SF2 thruster through Mercury’s Joystick Piloting for Inboards system. It brings the key JPI components together so the joystick, thruster, and inboard controls all speak the same language. Once installed, slow-speed maneuvering feels far more controlled, especially when you’re squeezing into a slip or dealing with wind and current.

Key Features
 • Single-Engine JPI Kit – Built for inboards running one SF2 thruster.
 • Clean Thruster Integration – Lets the joystick command the thruster smoothly.
 • Low-Speed Control – Helps with sideways moves, pivots, and tight docking.
 • JPI-Ready Hardware – Includes the components needed for proper system communication.
 • OEM Compatibility – Works directly with Mercury JPI setups.

Engine & Boat Compatibility
 • Joystick Piloting for Inboards
 • Single-engine inboard boats
 • Side Power SF2 thrusters
 • SmartCraft network

Performance & Practical Benefits
Once the kit is in place, the boat reacts more naturally when you ease the joystick—no big delays, no jumpy corrections. The thruster and drivetrain work together instead of fighting each other, which makes tight-spot maneuvering feel lighter and more predictable. It’s the kind of upgrade that immediately reduces stress around docks.

Why Buy OEM
OEM JPI components are built to pair cleanly with Mercury’s calibration and wiring standards. Everything plugs in without improvising, and the system stays reliable over seasons of use—no odd behavior from mismatched parts.

FAQ
Q1: What does this kit actually do?
A: It lets a single-engine inboard setup use an SF2 thruster with Mercury’s JPI system.

Q2: Do I still need an adapter harness for SF2?
A: Only if your thruster requires one—most SF2 setups use this kit as part of the main installation.

Q3: Is calibration required after installation?
A: Yes, JPI always needs a quick calibration so everything syncs correctly.

Q4: Will it work for saltwater boats?
A: Absolutely—just keep connectors and thruster hardware rinsed and clean.

Q5: What if the joystick feels delayed after install?
A: That usually points to calibration or a connection issue, not the kit itself.
