Any suggestion on getting access to fresh water tank to find and repair leak in 2002 SCR 3300 Maxum. under cabin floor

How do I gat full access to my water tank on a SCR 3300. Have a leak and notice a very small leak by two plugs. But that is looking under floor from Aft Cabin, behind the shower and AC tank. Would blike to be able to check whole tank and repair

The 36-gallon fresh water tank on a 2002 Maxum 3300 SCR is located under the floor of the cabin, specifically beneath the floorboards in the mid-cabin/aft berth area.

To access the tank and its associated water pump, follow these steps:
  • Locate the access panel: Look for the forward floor panel on the aft berth floor.
  • Remove the carpet and screws: You will need to pull back or remove the marine carpet to locate the panel. The sump pump/tank wood panel is typically secured with a few screws and a small amount of adhesive.
  • Slide the panel: Once the screws are removed, carefully slide or lift the panel back towards the aft wall to gain access to the tank.
