Engine Compatibility
Used in selected PCM / Pleasurecraft Marine and Crusader inboard engine applications. Current supportable references also connect this washer with 6.0L manifold mounting stud hardware usage, but exact fitment can still vary by engine model and assembly location.
Serial Number Fitment Notice
Fitment can vary by engine model, mounting location, and hardware stack-up. Always confirm compatibility by engine model, serial number, and the original hardware reference before ordering.
When This Part Needs Replacement
Replace this lock washer when the original hardware is corroded, flattened, damaged during disassembly, or no longer suitable for secure reassembly in the intended location.
Installation Notes
Confirm the correct application before installation and compare the new washer to the original hardware during service. Inspect the related bolt, stud, nut, and mating surfaces so the replacement is installed into a clean, properly supported assembly. On manifold-related service, matching the exact washer size and hardware stack matters.
Alternate/Superseded Part Numbers
Current references identify this item as 93930000. Related listing language commonly describes it as MED M8 ZN lock washer or split lock washer.
Parts Desk Insight
This is the kind of small hardware that is easy to reuse without thinking about it, but on a marine engine, fresh locking hardware can save you from a loose fastener and repeat work later. The smart move is to match it by part number and by where it sits in the assembly.
