Mercury – JPI Dual Thruster Kit SF2 | Control System | 98-8M0171474

Overview
This JPI dual thruster kit is built for inboard boats running two Side Power SF2 thrusters with Mercury’s Joystick Piloting for Inboards. It brings the hardware the system needs so the joystick can control both thrusters and the drivetrain as one smooth unit. Once everything is hooked up, slow-speed maneuvering—slides, pivots, tight turns—feels a lot more controlled and less stressful, especially on windy days or when space is tight.

Key Features
 • Dual-Thruster JPI Kit – Made for inboard boats equipped with two SF2 thrusters.
 • Full Joystick Integration – Lets the joystick command both thrusters together.
 • Better Low-Speed Handling – Helps with sideways moves, fine adjustments, and tight docking.
 • JPI-Ready Components – Provides the parts needed for proper network communication.
 • OEM Compatibility – Designed to drop right into Mercury’s JPI system.

Engine & Boat Compatibility
 • Joystick Piloting for Inboards
 • Dual-engine or single-engine inboards using dual SF2 thrusters
 • Side Power SF2 thrusters
 • SmartCraft network boats

Performance & Practical Benefits
With both thrusters tied cleanly into JPI, the boat responds more confidently to small joystick inputs. You can ease it sideways, rotate the bow, or settle into a slip without the boat feeling like it’s guessing at your commands. Both thrusters and the drivetrain work together, making close-quarters handling feel smoother and more predictable.

Why Buy OEM
OEM JPI components are built to match Mercury’s wiring and calibration standards. Everything fits right, communicates properly, and avoids the odd behavior that can show up with mismatched aftermarket parts.

FAQ
Q1: What makes this kit “dual”?
A: It’s designed to integrate two SF2 thrusters into a single JPI inboard system.

Q2: Do I need an adapter harness?
A: Only if your specific Side Power thruster requires one—many SF2 setups pair directly with JPI when using this kit.

Q3: Is calibration required?
A: Yes—JPI always needs a calibration pass after installation.

Q4: Can it handle saltwater use?
A: Yes. Just keep connectors rinsed and the thrusters maintained.

Q5: What if the joystick feels slow or uneven afterward?
A: That usually points to calibration, wiring, or a connector issue, not the kit itself.
