Question

My v hull boat get lots of water in hull after 10 or12 hrs ,where is most common place it would be leaking?

Answer 1

you could have a fracture at the front bow section,maybe where you've hit a bank,or if an internal engine, maybe the stern gland seal has gone, why not leave some dry rags around the bow section?,if they get wet early, then this would point to the front,more info as to what type or size would help

Answer 2

Is the boat an outboard, inboard/outboard or an inboard.  Knowing what kind of engine system in it may help to ID where or what the leak is coming from.  

1.  If you have an Inboard, the engine has a propeller shaft going though the hull and the shaft's packing may be leaking.

2.  If you have an inboard/outboard, then you may have some water leaking around where the shield that clamps between the outside of the hull and to the inside may be leaking.

3.  If you have an outboard, that hangs on the stern and is not an issue.

What kind of hull do you have?  

1.  Fiberglass, can have a hole in one place and leak in from another place and is wicked down through a foam liner.

2.  Aluminum, that has rivets can leak there or from a crack in a weld.

3.  Wood, the caulking can be needing replacement.

Not knowing any of those issues, your best bet is to put the boat on a trailer (if it can be) and fill it with water until you have about ten inches in it and look for dripping water.  Much more than that an the boat will get too heavy for the trailer and could damage it.

If you have a engine inside the boat, look where the sea water is  pumped into it for cooling system and make sure that none of the fittings are leaking when the engine is running.

You can email me and I can give you some more places to check once I know what you have.

Good luck and carry a big bucket until you find the leak!

Answer 3

You may find it easier by taking it out of the water and pour water into it.

Tilt the boat in different angles and inspect the underside.

You may have to wait for a time, maybe not.

It's the only thing I would do.
