another thing to look at is a swivel pin leak. I had that issue two years ago. On the older Bravos they did not include a grease zert on top of the drive, sot he swivel pin would get rusty and destory the seal. Good way to find out if this is your issue is while your in the water have 3-4 people stand on the back of the boat and kind of make the boat rock back and forth. Look at the transom mount on the inside this is where the engine connects to the drive, kind of a round oval black metal plate(sorry if im talking to you like you dont know) you should see a steering arm come out of square rectangle shape on the top of that transome mount, if when people are on the back of the boat and water is coming through that hole you need to fix your swivel pin seal and probably the swivel pin yourself. This means pulling engines, BUT there a well known reputable way to do it without pulling the engines and cost about 50 bucks in parts and anybody can do it. Anyways heres the link and if you do it make sure you rent his tools. http://www.jrmarine.com/instructions.htm

I read a similar thread awhile back about a Fountain owner getting water into his bilge. After some investigation he found the output hose on his rear bilge pump, which sat at or below the water line during certain operating conditions, was pressurizing and back feeding his bilge pump, pushing water into his bilge. He fixed the problem by adding a check-valve (purchased from Defender.com) in-line with the output hose of his bilge pump.
On the flip side, a boat tech recently told me inserting a check valve in-line with the bilge pump output hose can introduce back pressure on an operating bilge pump causing premature failure of a bilge pump. I get a bit of water in the bilge of my boat too, but because of what my boat technician said I hesitate to try the check-valve trick. Does anyone have long term experience with using a check-valve on their bilge output hose?
