Sierra Stator 18-5877-1, Replaces 432230, for Johnson/Evinrude 185-300 HP Outboards

The Sierra Stator 18-5877-1 is a replacement stator for Johnson/Evinrude outboard motors, engineered to restore the charging and ignition-timing function that the original equipment stator provides. As the stator wears or fails, an outboard can lose charging output or develop ignition irregularities, and this part is built to match the original fit and electrical output so the motor's charging system operates as designed.

This stator carries part number 18-5877-1 and directly replaces OEM number 432230. It is application-specific to Johnson/Evinrude outboards in the 185 HP through 300 HP range, with coverage varying by horsepower: 185 HP covers 1993 through 1994, 200 HP, 225 HP, and 250 HP each cover 1993 through 2001, and 300 HP covers 1993 through 1995. The package includes the stator only, ready for installation on a compatible outboard. It weighs 4.5 pounds.

Note that Johnson/Evinrude 150 HP and 175 HP outboards from 1993 through 2006 use a different stator, part number 18-5878, which is a separate SKU from this 18-5877-1 part. Confirm your outboard's horsepower and model year against the fitment listed below before ordering to ensure you receive the correct stator for your engine.

Frequently Asked Questions

What does the Sierra Stator 18-5877-1 fit? The 18-5877-1 fits Johnson/Evinrude outboards from 185 HP up to 300 HP, with coverage of 1993-1994 for the 185 HP, 1993-2001 for the 200, 225, and 250 HP, and 1993-1995 for the 300 HP.

Is the 18-5877-1 a direct replacement for OEM number 432230? Yes, Sierra stator 18-5877-1 is built as a direct replacement for OEM part 432230 on covered Johnson/Evinrude outboards.

How much does this stator weigh? The Sierra Stator 18-5877-1 weighs 4.5 pounds.

What is included when I order this part? The 18-5877-1 ships with the stator only; no additional hardware or components are included.

Will this stator work on a 150 HP or 175 HP Johnson/Evinrude outboard? No. Johnson/Evinrude 150 HP and 175 HP outboards from 1993-2006 use a different part, Sierra stator 18-5878, which is a separate SKU from the 18-5877-1.

Does the 300 HP application cover the same years as the smaller horsepower models? No, coverage differs by horsepower: the 300 HP application for the 18-5877-1 runs 1993-1995, while the 200, 225, and 250 HP applications run 1993-2001.

Is this a genuine OEM part or an aftermarket replacement? The 18-5877-1 is a Sierra-brand replacement stator manufactured to replace OEM part 432230, rather than an original Johnson/Evinrude-branded part.

How do I know if my outboard needs a new stator? A failing stator on a Johnson/Evinrude outboard typically shows up as reduced charging output or ignition timing irregularities; if your covered horsepower model is experiencing these symptoms, the 18-5877-1 is the matching replacement stator.

What horsepower and year combinations use the 18-5877-1 versus the 18-5878? The 18-5877-1 covers 185, 200, 225, 250, and 300 HP Johnson/Evinrude outboards, while 150 HP and 175 HP models use the separate 18-5878 stator; check your engine's horsepower before ordering.

Can I cross-reference this part using the OEM number instead of the Sierra number? Yes, OEM number 432230 corresponds to Sierra part 18-5877-1, so either number can be used to identify the correct stator.
