boat water inflow

[sea mania]

My boat is Regal 2007 1900 series.
Water is pooling in the bottom of the engine room while the boat is running.
When the ship shakes, the water is all over the engine, causing the parts to corrode quickly.
I can't find where the water is coming from.
When I put my boat in the water, the water doesn't get pooled on the floor, but when I open the lid of the engine room while I'm driving, I find it watering on the floor.
Bilge pump operation is water pooled on the floor, but be water on the nerves.
How can i find the location of the leak?

Check the transom. Is it flexing under load?

Need lots more info... is it an mercruiser sterndrive? Alpha? Bravo? Could be a leaking bellows, exhaust y pipe flange gasket, hole in exhaust from worn flappers.... it's a long list and we need help to help you.

While there is water in the boat throw some food color dye ( red shows up well ) in there as well,
As the water eventually drains out the dye will leave a mark on the hull which will show where the water is coming from,

" could " just be something " simple "
like the wrong or worn thread on a bung/s

Sorry.
my engine is volvopenta 4.3 and sx-a sterndrive.

Water only comes in while the motor is running.

Assuming this is a raw water cooled motor and does not have a heat exchanger

Most probable parts would be the raw water pump seal, then the engine circulating pump
