Yamaha Pin, Dowel (99530-10114-00) doesn’t look like much—just a sleek 10 mm stainless-steel rod with softly chamfered ends—but it’s the quiet reason your outboard pulls hard without extra vibration. Slide it into the crankcase or gear-case seat and the housings line up instantly, so gaskets seal, oil stays put, and bolts thread home without fighting mis-matched holes. Salt spray? No problem. Yamaha’s corrosion-resistant finish keeps the surface smooth season after season.

Why keep a few in the kit?

• OEM-exact fit for a wide range of Yamaha two-stroke and four-stroke platforms, from portable F2.5s to big-block V-6s
• Hardened to 55 HRC to resist flattening under prop shock and knocking loads
• Precision 14 mm length holds tighter tolerances than most aftermarket pins
• Smooth lead-in radii let you press it home with a thumb, not a hammer

The practical payoff is simple: quicker rebuilds, truer alignment, and less wear on everything from main bearings to backing plates. At the price of a cup of coffee, this little dowel spares you the headache of crooked casings—so you can get back to chasing the next tide shift instead of fighting with engine parts
