That barnacle could certainly affect the flow but was not present when I got the sensor. I would like to see three things happen: - Remove the external strainer. Depending on the design it may mean a complete thru-hull replacement.
- Addition of a raw water strainer instead. It is easily cleaned out inside the boat.
- A fresh water flush of the engine when cleaning up the boat after a sail. With a flushing Tee and valve installed, it's a 5 minute process.
