2-Stroke Ban

Are 2-stroke engines allowed to launch on Lake Tahoe or the surrounding lakes in the area?

The Tahoe Regional Planning Agency (TRPA) prohibits the launch and use of all carbureted 2-stroke engines. This generally applies to outboard motors and personal watercraft (jetskis). The TRPA does allow all 4-stroke engines and Direct Fuel Injected (DFI) 2-stroke engines. If your watercraft/engine has a California Air Resources Board (CARB) Star rating on it, it is allowed on the Lakes of the Tahoe Region. Some common outboard engines that are allowed:

  • Evinrude E-TEC (2-stroke DFI)
  • Mercury Optimax (2-stroke DFI)
  • Yamaha High Pressure Direct Injection (2-stroke DFI)
  • All Honda engines (4-stroke)

If you are unsure about whether or not your watercraft/engine is allowed on the Lakes of the Tahoe Region, please contact Steve Sweet, ssweet@trpa.org  775-589-5250.
