Default Water in bilge

Have a 1999 scr 3000 and am getting significant water under the starboard engine in the bilge. This problem has now entered its second season. The gimbal housing and transom bracket were replaced this off season. Manifolds and risers are new. I am stumped. Looking for any ideas. It seems to take on water when boat is loaded and high rpms. Mechanic and I on boat no leak. Going 2200 rpm with load no leak. Any help is appreciated. Thanks

Lay down some oil absorbent pads under the engine to determine the general location. Could be raw water inlet hose, bad freeze plug, ...

Using a pro cam stick to allow you to film when on plane may help.

Thanks I am going to try a camera. The pads won't work bc it literally is gallons coming in not little drips.

If it's that much water any mechanic worth half his weight should be able to find the leak easily.

The very specific circumstances make it difficult to find. Having a full load on the boat and access to the bilge is not easy. In the slip at idle not a drop of water. I ordered a camera last week with a monitor so as soon as that comes hopefully there will be an answer.

I use baby powder to find pesky leaks.

"Puff" powder on areas that you want to check.
Be sure to include areas around the transom plate.

Powder will wash off once the diagnostics are done.

Is it salt water or fresh? Warm or cold?

When you say "The gimbal housing and transom bracket were replaced this off season" are you saying the entire inner and outer transom assembly?

Since it takes X number of passengers and high rpms where are the passengers seated? Sounds like more aft weight and the stern settling down which would mean either the transom assembly is further under water and leaking or its seal the boats transom is leaking in the upper area.

Both were replaced. The seal around the upper steering shaft was bad and the gimball housing was corroded. Engine was moved and the inner transom bracket was replaced as well. All new bellows.
