Troubleshooting & FAQ

How do I confirm this carburetor fits my Tohatsu or Nissan engine?
This carburetor is specifically designed for 4 HP and 5 HP 2-stroke models like the Tohatsu M5B, NS5A, and NS5B. The best way to ensure compatibility is to match your old part's number to one of the cross-referenced numbers: 369-03200-0, 369-03200-1, 369-03200-2, or Sierra 18-7206.
