Sierra Carburetor Kit 18-7291, Replaces 346871220M, for Nissan/Tohatsu Outboards

The Sierra 18-7291 Carburetor Kit is a carburetor rebuild kit built for Nissan and Tohatsu outboard engines, with a documented cross application to Yamaha outboards as well. It is designed to restore carburetor performance on engines where the original carburetor components have worn out, using components that meet or exceed the original equipment part it replaces.

On Nissan applications, one kit is used per engine on 25 HP and 30 HP models, while two kits per engine are required on the 45A2, 50C, 60C, and 70A models. For Yamaha outboards, three kits of the Sierra 18-7291 are used to equal one Yamaha 6H1-W0093-01-00 kit, giving buyers a straightforward way to source the equivalent rebuild coverage. The kit carries a machined exterior finish and is a lightweight component at 0.05 pounds. As with all Sierra parts, it is covered under Sierra's standard customer satisfaction warranty.
