Sierra 18-99224 Johnson Evinrude Stator, 3 Cylinder 9 Amp, Replaces 763762 584766 583779 584236, Fits 1989-1998 60 65 70 HP

The Sierra 18-99224 is a 3 cylinder, 9 amp stator built as a replacement ignition charging component for Johnson and Evinrude outboard engines equipped with S.L.O.W. (Speed Limiting Overheat Warning). The stator is a core part of the outboard's charging and ignition timing system, generating the AC voltage that the engine's power pack or rectifier uses to fire the ignition and maintain the S.L.O.W. Warning circuit. As the original stator ages, windings can weaken or short, leading to hard starting, weak spark, erratic tachometer readings, or loss of charging output -- installing a fresh Sierra 18-99224 restores factory electrical output on applicable engines. This stator is designed as a direct replacement for the OEM Johnson/Evinrude stator on the covered engine range, crossing to several factory Johnson/Evinrude part numbers so it can be ordered using either the Sierra number or the original OEM number. It is intended for outboard engines in the 60, 65, and 70 HP range built with the S.L.O.W. System.

Frequently Asked Questions

What engines does the Sierra 18-99224 stator fit? The Sierra 18-99224 fits Johnson/Evinrude outboard engines with S.L.O.W. (Speed Limiting Overheat Warning) rated at 60, 65, and 70 HP, built in the 1989-1998 range.

Does the 18-99224 stator replace an OEM Johnson/Evinrude part number? Yes, the Sierra 18-99224 crosses to OEM Johnson/Evinrude part numbers 763762, 584766, 583779, and 584236, so it can be ordered as a direct replacement using any of those original numbers.

How many amps does this stator produce? The Sierra 18-99224 is a 9 amp stator, matching the charging output of the original Johnson/Evinrude unit it replaces.

Is this stator for a 2 cylinder or 3 cylinder engine? It is a 3 cylinder stator, built specifically for 3 cylinder Johnson/Evinrude powerheads in the 60-70 HP range with S.L.O.W.

What is S.L.O.W. And why does it matter for this stator? S.L.O.W. Stands for Speed Limiting Overheat Warning, an ignition-based protection system on certain Johnson/Evinrude engines. The 18-99224 stator is built for engines equipped with this system, so it maintains the correct signal for the S.L.O.W. Warning circuit.

How much does the 18-99224 stator weigh? The Sierra 18-99224 stator weighs 2.6 pounds.

What are common symptoms of a failing stator that this part fixes? A failing stator on a covered Johnson/Evinrude engine can cause weak or no spark, hard starting, erratic charging, or false S.L.O.W. Warnings; replacing it with the Sierra 18-99224 restores the original electrical output.

Is the Sierra 18-99224 a genuine Johnson/Evinrude part or aftermarket? The 18-99224 is a Sierra-branded replacement part engineered to match the output and fit of the original Johnson/Evinrude stator, cross-referencing to OEM numbers 763762, 584766, 583779, and 584236.

Will the 18-99224 work on a 2-cylinder Johnson/Evinrude outboard? No, the Sierra 18-99224 is built for 3 cylinder Johnson/Evinrude engines with S.L.O.W. In the 60, 65, and 70 HP range.

Can I use the Sierra number or the OEM number to order this stator? Either works: the Sierra 18-99224 is the same stator as OEM numbers 763762, 584766, 583779, and 584236, so it can be ordered under any of those references.
