Hey JTKashou,
Ran into the same problem. Two of the 3 are screws, and one is a bolt that has a nut on the inside which holds a grounding wire. Take that nut and wire off, push the bolt out and remove the other two screws. Take the exhaust cap off. You should see where the water is coming through then. Dry it out really well and seal the hull side with 3M4200 sealant as it will need to be done every decade or so. Put the cap back on and should be good-to-go!
