Troubleshooting
8Symptoms & remedies
| Symptom | Remedy |
|---|---|
| Temperature above 205°F (97°C) | Shut off the engine immediately. Use the Trouble Shooting Guide to isolate the cause of the overheat. Allow the engine to cool and then remove the cap slowly, using protective clothing. |
| Temperature above 200°F (94°C) | Watch the temperature gauge regularly and turn off the unit if the temperature rises above 200°F (94°C). Repeat the troubleshooting process. |
| Low oil pressure | Check the engine crankcase oil level. If the oil level is low, fill with recommended lubricating oil and restart. Watch the oil pressure gauge carefully and shut off the engine if it does not show a normal reading after a few seconds of operation. |
| Engine overheating | Shut down the engine and investigate the cause of overheating. Do not exceed 800 RPM when shifting marine gear to avoid damaging the reverse gear. |
| Maximum rated RPMs exceeded at full throttle | If you cannot reach your maximum rated RPMs at full throttle, either your propeller is too large or bottom growth is slowing the boat. Ensure proper propeller usage. |
