There should be a manual release valve/screw near the outboard saddle. Release this and it will lower. Looks like you'll need to strip out the motor for a closer look.

I too had the same problem with my tohatsu on my old boat, found water in it, stripped it, the dirty water had damaged the brushes, managed to get some brushes from a Morris minor dynamo and file them down.

Lasted about two years, I finally sourced a motor front the US and fixed for good, just make sure you change the seal as the folks say as the motor sits alot of the time under the water line. Best of luck
