Hi all, I have a 1986 Bayliner bowrider 18 foot. My problem is water entering the back. On either side of the motor shroud ("doghouse") there are two seats which are removable and there is storage space underneath. The one on the port side takes in water when raining. We can't find the source of the leak anywhere. The reason for concern is we had to replace a piece of rotten floor already and we are thinking the water is running from storage space to the middle of the floor. Is this common? Any idea how the water is getting in? By the way, the boat has a water proof tonneau on it when it is sitting.
