Leaking from the hull

[2014 Malibu vlx]

Wandering if anyone would have any insight on my issue? I have a 2014 Malibu vlx with a Monsoon 350 SS and am experiencing a water/antifreeze leek (after the winterization) where the prop shaft goes through the hull. I'm not sure if this has been an ongoing problem but it did seem like the bilge pump would kick on quite often this season. Could this be a seal or a cracked block or something completely different.

Need to find if the leak is hull or motor. Does the pump run while at the dock for days or weeks ?

The boat is kept on a lift, so only while underway

Sounds like you have a dripless coupler ,that needs to be adjusted . Usually the water feed comes from the exhaust manifold. Or it could be Teed into a raw water hose . It is not Teed into a closed part of the cooling system that has anti- freeze running through it . I believe the Tides or PSS version has 3 allen head screws that have to be removed to expose 3 more allen screws below them . This is on the SS compression ring closet to the hull . Those are loosened ,not removed . Next you compress the ribbed bellows ( which cover graphite disc ) a little bit as they wear over time . Tighten up the Allen's and put the top ones back in . Any more info or pictures would be helpful.

Replied late last night , the coupler is adjusted when the boat is in the water and water is " leaking " through the coupler . The fixed part is attached to the hulls shaft tube . The adjustment ring is closet to the transmission and compressed towards the shaft tube ( stern ) . There is a base setting when initially installed ,something like 3/4 " . This is probably where your water was coming in over the summer.
