I have water leaking into the bildge , it is coming in at the bottom of the inner transom plate. It is a 1996 Alpha 1 . I found a hole in the shift cable bellows and replaced the bellows but I still have water leaking in. When I pulled the drive to replace the shift cable bellows there was no water in the u-joint bellows and the bellows was inspected and was ok. How do I test to find out where the water is entering the boat from.
