how much leaking into the beilge normal?

[lime4x4]

91 19 foot sea-pro boat.Fiberglass inside and out.I have the problem of getting into the beilge area.I've taken all the thru hull drain holes out and resealed them all.The water seems to start under the right rear seat area at the transom.Then after awhile it starts to spill over to the beilge area under the motor.The beilge pump runs maybe once every 30 min or so and it only runs for 1 to 2 min max.It's a 800 gph pump set up on a float.I c no cracks in the hull and i thought these boats were a double hull design.I've also attached a pic of the boat in question

Any through bolts for a swim platform you have not checked.Engine bracket bolts? Or spray coming in somehow? It looks like an outboard correct?

it's an I/O mercruiser.That's my little 9.9 hp kicker but that's on the opposite side as to where the water appears to be coming in.I don't think it's spray cause we can be out in the lake fishing just drifting for several hours and the beilge pump kicks in every 30 min or so.

Oh and mounting for the kicker is sealed.And the boat has no swim platform.And i also have the engine cover off when trying to find this leak and it's dry around the transom where the engine and sterndrive attach

Hmmm, water is tricky. It can make its appearance quite a ways away from where it is actually coming in. If your pump is only kicking in every 30 mins or so, then it's obviously a very slight leak. I've heard of people filling the bilge while on the trailer to see where it leaks out.​

well that's just it.The leak starts over in the right rear under the seat where the battery and blower motor are.Which is a good 4 inches higher then the beilge.Once that is filled it starts to leak over into the beilge area.I really don't want to fill that area with water cause from the looks of it it goes up to the front of the boat and there is also a 4 inch plastice pipe that starts there and goes up just past the sterring wheel

Next time your on the lake start dabbing around with a paper towel, start high. When it starts get wet, bingo.
