Why is my Yamaha FZR 1800 Boat slow or losing power?
- IihowardJul 27, 2025
If your Yamaha Boat is slow or losing power, there are several potential causes. First, ensure the shift lever is fully engaged by pushing it forward until it stops. If the Yamaha Security System is active, select normal mode. Check for and clean any cavitation. If the engine is overheating, clean the jet intake and cool the engine. Also, check the oil pressure; if low, add oil. A faulty spark plug can also cause this issue, so replace it if necessary. Make sure the spark plug cap is properly connected.
