jetunit Stator for Mercury/Mariner Outboards — 16A Ignition Stator, Fits 30–125 HP 2-Stroke SportJet (1987–1997)

JETUNIT stator 174-9710K1 is a direct-fit 16-amp ignition stator designed to replace OEM units on many Mercury/Mariner 2-stroke outboards from 30 to 125 HP (1987–1997).

This stator assembly from JETUNIT restores charging and ignition performance for older Mercury/Mariner SportJet and Force 2-stroke engines. Engineered to match the electrical output and mounting pattern of common OEM part numbers, it’s intended for mechanics and boat owners who need a reliable replacement for a worn or failed stator on models listed in the compatibility range.

Which engines and part numbers will this stator fit?

The JETUNIT stator is made to replace a wide range of OEM part numbers used on Mercury and Mariner two-stroke outboards. It covers multiple cylinder counts and horsepower ratings commonly found on SportJet and Force models built between 1987 and 1997.

• Compatible HP range: 30, 40, 45, 50, 55, 60, 65, 70, 75, 80, 90, 95, 100, 115, 120, 125
• Supports 2- and 3- and 4-cylinder 2-stroke configurations used on SportJet platforms
• Cross-references: 174-9710K1, 398-818535A17 and other OEM numbers listed by manufacturer

How does this stator affect my outboard’s charging and ignition?

A properly functioning stator provides the alternating current necessary for charging the battery and powering ignition systems. Replacing a faulty stator with a matching unit restores steady voltage output, improves spark reliability, and helps maintain battery charge while the engine runs.

• Delivers approximately 16 amps suitable for the listed engine sizes
• Replaces worn or damaged windings and connectors that cause weak spark or no charge
• Designed for plug-and-play installation where mounting and wiring match the OEM layout

What should I check before buying and installing this part?

Confirming fitment and inspecting related components reduces rework and ensures a successful repair. Check your engine’s model year, horsepower, and the existing stator’s part number before ordering.

• Verify OEM part numbers stamped on your old stator or listed in your service manual
• Inspect the flywheel, keying, and connector condition for damage or corrosion
• Consider replacing associated seals, gaskets, or ignition coils if they show wear

What warranty and support come with this replacement stator?

JETUNIT includes a one-year warranty and customer support to help troubleshoot fitment or performance concerns. The warranty covers defects in materials and workmanship under normal use; follow the supplier’s return and claim instructions if issues arise.

• 1-year limited warranty included
• Customer service response typically within 24 hours for troubleshooting
• Advice to check manufacturer recommended part numbers before installation

Who is this for: The JETUNIT stator is aimed at marine DIYers, professional mechanics, and restoration projects working on late‑1980s to mid‑1990s Mercury/Mariner two‑stroke outboards. If you need a replacement that cross-references common OEM part numbers and restores charging and ignition performance for SportJet and Force engines in the 30–125 HP range, this stator offers a practical, warrantied option. Always confirm exact part compatibility with your engine serial and model information before purchase.
