The fresh water tank is mounted sideways just down the companionway stairs on the 42. If it's leaking, you likely wouldn't get water in the ER, it would go to the forward bilge. If it is the water tank, it's a pain. A weld failed on ours a few years ago. They had to cut an access into the floor, sawzall the old tank out in pieces and replace with a new poly tank that ran lengthwise.

If you're getting water in the engine room on the port side, check the fittings on your water heater. If you find out that it is the tank, pm me your email and I can send you all the details of where to get it made etc as they've done a few of them...
