A little water

Our speed gauge hasn't been working so today I pulled the paddle wheel thru hull. Previously, the only water I've let into the boat was when we pulled the raw water intake. That pipe is less than 50% as big as this one and the water volume was modest. This one has a cap that unscrews and then you pull the cylinder out. That caused quite a gusher. Luckily the bung for this an exact copy of the functioning unit and slid right in. So it wasn't all that much water in the end but still surprising and a little unsettling to see dirty water pumping in. I should've taken some photos of the debris, seaweed and mud on the paddle wheel. I cleaned it with a brush until it spun freely. Then replaced the thru hull, oriented the arrow on the housing to parallel to the keel, and slipped the safety wire over the unit which acts as fail safe (it wasn't on there when I started this project).
