    git a 2904 269DA. I cleaned the bildge dry and didn’t use it and no water got in. I get water in my bildge when I drive the boat. Any suggestions?

    How much? Only when you drive or when the engine is on, sitting at the slip? It could be anything from swimmers drippings, a leaky hose, water pump, etc.

    hull to deck joint, steering/hinge pins, hose or hose clamp on motor......my bet is the hull to deck joint back corners

    Mine was from a leaky water heater that was only used while running.

    With that much water it should not be too hard to find the source. Have someone drive and you watch in there with the hatch open. I sure hope your bilge pumps are up to par :)

    I am thinking hose or raw water system leak if you are getting that much when on plain and running. That would be the first place I look. Also look at your shafts going from motor through transom assembly. If they are wet and or have some rust - points to steering pin seals. Either new transom assembly or kit to replace pins and seals. Just did both of mine using the kits. It is a Bravo 3 thing. As stated above- with that much water, should be easy to see where coming from observing while it is running. Hoping it is a hose, easy and inexpensive. :)

    If you got no water in the boat when it's not being used then it must have something to do with the engine. Water being pulled in and circulated for engine cooling means there are many hoses and connections that can leak. Even the water pump on front of the engine block can leak. If two gallons of water is in the bilge then the leak is big and should be easy to find. Run the engine at idle and leave the engine hatch open, watch for water to appear. Be careful of the belt turning on the engine.

    Set up a go-pro or other video camera in the bilge and go for a ride.
