Stop the engine first
If propulsion changes suddenly, move to a safe place if possible and switch off before inspecting. Keep hands away from moving machinery and secure the controls.
Use the weed hatch correctly
Follow the boat's instructions, check the waterline and reseal the hatch fully after clearing debris. Never operate the engine with the hatch unsecured.
Check the result
Test gently in clear water. If vibration remains or a line may have damaged a seal, seek professional help rather than forcing the boat onward.
