Sierra Racing Stator 18-99285 for Mercury Mariner 6 Cylinder Outboards, 16 Amp

The Sierra Racing Stator, part number 18-99285, is a high-output charging component built for Mercury Mariner 6 cylinder outboard engines. Rated at 16 amps, this stator supplies the charging current needed to keep the engine's electrical system and battery properly powered during operation, an important consideration for racing and high-demand outboard applications where a dependable charging source is critical. The stator mounts within the outboard's flywheel area and works in conjunction with the engine's ignition and charging circuit to generate AC current, which is then rectified to charge the battery and run onboard electronics.

Built to withstand the heat and vibration found inside a running outboard powerhead, this stator is designed as a direct fit for the 6 cylinder Mercury Mariner engines it is intended for. Replacing a worn, weak, or failed stator with part number 18-99285 restores consistent charging output and helps prevent battery drain or no-charge conditions on the water.

Frequently Asked Questions

What engines does the Sierra 18-99285 stator fit? Part number 18-99285 is built for Mercury Mariner 6 cylinder outboard engines.

How many amps does this stator put out? The 18-99285 racing stator is rated at 16 amps of charging output.

Is 18-99285 an OEM or aftermarket part number? 18-99285 is the Sierra manufacturer part number for this racing stator; it is not an OEM Mercury number.

How much does the stator weigh? The Sierra 18-99285 stator weighs 3.2 pounds.

What does a stator do on an outboard engine? On a Mercury Mariner 6 cylinder outboard, the stator generates AC current as the flywheel spins, which is rectified to charge the battery and power onboard electronics.

Why would I need to replace my outboard's stator? A failing stator can cause weak or no charging output, leading to a drained battery; installing the 18-99285 racing stator restores the engine's charging performance.

Is this stator designed for racing use? Yes, the 18-99285 is designated as a racing stator, built for the higher charging demands of performance Mercury Mariner 6 cylinder applications.

What is the UPC for this part? The UPC for the Sierra 18-99285 stator is 808282395841.

Does this stator include mounting hardware? The 18-99285 listing covers the stator itself; check your engine's service manual for the mounting hardware and connector specifics needed for installation.

Can this stator be used on 4 cylinder Mercury outboards? No, the 18-99285 is built specifically for Mercury Mariner 6 cylinder outboard engines.
