Camotokiit Yamaha Poppet Valve Kit — Fits 115 to Z300 Outboards, Direct-Fit Complete Replacement

Camotokiit’s poppet valve kit delivers a complete replacement set engineered to fit Yamaha 115 through Z300 horsepower outboard engines, replacing OEM part 90501-16M11 and related numbers.

This kit contains new poppet valve components designed as direct-fit replacements for several Yamaha OEM references (90501-16M11, 60H-12416-00-00, 90480-20M05-00). Supplied as a new, ready-to-install assembly, it helps restore proper valve seating and operation in compatible outboard cylinder heads. The parts are intended for mechanics and boat owners seeking a reliable replacement when rebuilding or repairing Yamaha four-stroke powerheads from 115 HP up to Z300 models.

Which Yamaha models and OEM numbers does this kit replace?

The Camotokiit poppet valve kit is specified to match multiple Yamaha part numbers and is suitable across a wide range of four-stroke outboard sizes. It’s listed to replace the factory references so you can order with confidence when the original part number is known.

• Compatible with Yamaha 115 HP through Z300 HP four-stroke outboards
• Direct replacements for 90501-16M11, 60H-12416-00-00, 90480-20M05-00
• Also cross-references 60V-11382-A0-00 for select applications

How does this kit affect engine rebuilds or repairs?

Replacing worn poppet valves is a standard step in a cylinder head rebuild and helps re-establish correct valve sealing and timing operation. This kit supplies the valve components needed so technicians can reinstall or swap valves without sourcing multiple separate parts.

• Includes components to restore valve seating and compression integrity
• Simplifies parts procurement during head overhauls
• Reduces risk of mismatched components compared with piecemeal sourcing

What should I check before ordering to ensure fit?

Verify the OEM part number stamped on your existing valve or consult your Yamaha parts diagram for your engine year and model. Confirming the original number guarantees this Camotokiit kit matches the valves in your cylinder head and avoids returns or fit issues.

• Match your current part number to 90501-16M11 or listed cross-references
• Confirm engine HP rating falls within 115 to Z300 four-stroke range
• If unsure, compare visual details or consult a Yamaha service manual

What installation and maintenance tips improve longevity?

Install valves using the appropriate torque specs, valve spring compressor tools, and clean contact surfaces for reliable seating. Use fresh valve guide lubrication during assembly and inspect mating surfaces for wear to help the new components perform as intended.

• Use factory torque values and correct assembly tools
• Clean head and valve seats thoroughly before installation
• Inspect springs, guides, and retainers; replace if worn

Who is this for: The Camotokiit poppet valve kit is aimed at marine mechanics, boat owners performing engine service, and rebuild shops working on Yamaha four-stroke outboards from 115 HP through the Z300 series. If you’re restoring compression, addressing valve-related performance issues, or completing a head rebuild and you identified OEM part 90501-16M11 (or its cross-references), this kit provides the matched replacement components to get the job done efficiently.
