Product Details

The WSM 200-110-05 is a .5mm oversize piston ring set designed for OMC, Johnson, and Evinrude two-stroke outboard engines in the 85–300 HP range. This oversize ring set is intended for use during engine rebuilds where cylinders have been bored to a .5mm over-standard finished diameter. Sold individually — order one set per cylinder based on your engine's configuration.

Key Features:

  • .5mm oversize — designed for bored cylinders, not standard bore applications
  • Manufactured to meet or exceed OEM specifications for proper sealing and compression
  • Made in Japan to stringent quality standards
  • Direct replacement for OMC OEM part number 394930 (oversize variant)
  • Compatible with V4, V6, and V8 cross-flow and loop-charged engine families in the 85–300 HP range
  • WSM part number: 200-110-05

WSM (Water Sports Manufacturing) is a leading manufacturer of aftermarket powersports and marine engine components. The 200-110 ring set series is one of their most widely used marine piston ring lines, covering a broad range of Johnson and Evinrude outboard powerheads. Oversized rings must only be used with a cylinder bore that has been properly machined to the corresponding oversize diameter.
