I have a 1985 Sunsport that I bought from the original owner. The boat really is in great shape but i am fairly certain there is some stringer rot due to issues with the motor mount lag bolts spinning out.

This off season I was chasing an unknown leak due to some water getting in the bilge. I filled it up with water and had water coming up around the rudder plate. I pulled that up cleaned everything up and resealed it.

After getting it on the water we noticed water coming in around the rear driver side motor mount and bolts and water pooling at the point where the exhaust goes through the floor in that area. I think it is rather a leak around the exhaust where the flappers.

What else may cause water to be coming in that area?
