Product Details

The Sierra 18-4434 Powerhead Gasket Set is a complete gasket kit engineered for Nissan and Tohatsu 40–50 HP three-cylinder outboard engines. Designed as a direct OEM replacement, this comprehensive set includes all the critical sealing components needed for a thorough powerhead rebuild or top-end service.

Sierra International is a leading manufacturer of marine engine parts, and every product in their lineup is built to meet or exceed original equipment manufacturer specifications—ensuring reliable sealing performance and long service life.

Key Features:

  • Complete powerhead gasket set for Nissan/Tohatsu 40–50 HP 3-cylinder outboards
  • Meets or exceeds OEM recommended specifications
  • Replaces Nissan/Tohatsu OEM part numbers: 3C8-87121-4, 3C8871210M, 3C8871212M, 3C8871213M, 3C8871219M, and 3C887121CM

This gasket set is the ideal solution for technicians and DIY boaters performing powerhead overhauls, cylinder head service, or complete engine rebuilds on compatible Nissan and Tohatsu outboard motors.

I hope that the copper gaskets really seal.

Shipping was very fast. But no tracking number was given and pretty much was a guessing game. You all should work on that!
