Another common issue that you may need to troubleshoot is vibration. If you’re experiencing excessive vibration, you can start by checking the condition of the propeller. If you find any damage, you’ll need to remove it and bring it in for repair or possible replacement. If there’s no damage, the next step is to remove any seaweed or other debris that might have become entangled in it. While you’re at it, check the propeller shaft for damage. Once again, if you find damage, you’ll need to take it in for repairs. Lastly, tighten the motor mounting bolt and the steering pivot with a wrench. Restart the engine to see if the vibration has stopped. If not, it’s time to bring it in for an inspection. [links]
