A speed log paddle wheel. With the ring you can pull it out so that you can clean the paddle wheel without swimming under the boat or having the boat put ashore. It should be accompagnied by a dummy which you can place in the hole when the paddle wheel is removed. There will come some water in the bilge when you pull the transducer out. It will probably be stuck when you have never removed it. My advice is to try it when the boat is on land so you can make everything work properly and you avoid panic situations. On You tube there are several demonstrations. I will look them up.
