Hi, I have the same set-up on my sailboat. I’am facing an issue at the moment. When speeding up with the engine, a loud tick is occurring. It’s not related to the engine itselfs and it’s coming from the back of the boat. More gas results in a louder tick. I’am clueless what can create such a noise and severe vibration in the boat. Failed anode? Worn out buffer pads? Cavitation?
