We were out in the lake yesterday and pulled the boat and drained boat by removing the plug. There was a lot of water in the boat. How much I would say a constant stream of water for a few minutes. I store my boat with the motor down to not stress the bellows. The boat ran fine. I replaced the impellar recently and the motor ran cooler than it did before the repair. I did not notice oil in the water by the outdrive. My question is where should I look and if it is the bellows what is the best way to check them to make sure it is or isn't the bellows. I had the bellows done about four years ago. Thanks for any help.
