What to do if my Yamaha Boat watercraft is slow or loses power?
- SsuzanneromeroAug 13, 2025
If your Yamaha Boat watercraft is slow or loses power, several potential causes exist. The jet intake might be clogged, leading to cavitation, so clean it. The impeller might be damaged or worn, leading to cavitation, so have it serviced by a Yamaha dealer. The engine might be overheated, so clean it. The fuel filter might be clogged, or the fuel might be stale or contaminated, so have it serviced by a Yamaha dealer. The spark plug may be fouled or defective, or have an incorrect heat range, so replace it. The spark plug gap might be incorrect, so adjust it. The spark plug caps might be loose, so connect them properly.
