Product Details

The Wiseco 40038M10100 is a forged piston kit designed for Sea-Doo watercraft powered by the 1494cc 4-stroke engine. Machined to a 101.00mm (1.00mm oversize) bore with an 8.4:1 compression ratio, this kit delivers the precision fit and durability demanded by both performance riders and recreational enthusiasts. Each kit includes one piston, Wiseco rings, wrist pin, and circlips — everything needed for a complete piston replacement.

Key Features:

  • Aerospace-grade forged aluminum construction — forging compresses the material's molecular structure, aligning grain flow and increasing density for superior strength, reduced weight, improved heat transfer, and extended service life compared to cast pistons
  • 101.00mm bore diameter — 1.00mm oversize; cylinder resleeve required for proper fitment
  • 8.4:1 compression ratio — matched to OEM engine specifications for reliable power output
  • ArmorGlide skirt coating — reduces friction and wear for improved break-in and long-term durability
  • CNC diamond-turned finish — precision machining guarantees consistent sizing with no dimensional variation
  • Compatible with all cylinder bore compositions — cast iron, chrome, Nikasil, and boron composite cylinders
  • Kit includes: piston, Wiseco rings, wrist pin, and piston pin circlips
  • Engineered, forged, and machined in the USA in Mentor, Ohio

Wiseco is the only aftermarket piston manufacturer in the United States that produces pistons exclusively through the forging process, ensuring each piston meets the tightest tolerances using the latest 3D design techniques and finite element modeling. The result is a piston optimized for maximum strength-to-weight ratio — purpose-built for the high heat, high pressure demands of marine 4-stroke performance engines.
