Ocean 40 leaking thru hull forward bilge

Need help and info…. I have a through hull fitting that has been seeping water into the forward bilge for some time now.
The pump pumps it out every day but I was wondering if the seeping has made the hull/ keel area saturated and adding weight to the boat .?

I believe all Oceans in 2004 were solid fiberglass, it has had this slow leak since I purchased the boat over two years ago and I’ve had the boat pulled and blocked …. There has been no delamination . I also have a diver that scrubs the bottom every month and there has never been an issue .
I confirmed this morning that the through hull fittings are staying dry after I pump water out so now I’m not sure where it’s coming from !
It’s in the forward bilge close to the head but I tested the water and it’s definitely salt water .

Head is fresh water , have checked all thru hulls and all are dry… going to check all hose fittings in that bilge as well as the shower drain line today but seriously doubt that’s the cause of the slow leak.
My biggest concern was if the bottom of the boat/ keel was holding water .. thus adding weight but based on research the hull of the 40 ft ocean is solid fiberglass .

Need some help on my 2004 Ocean Yachts 40 SS

boat has the original Cat 3126 engines and gear boxes …. Can’t read info on gear box plates and I need to know the gear ratios…. ???

thanks in advance to anyone that can help !!

Thanks Captain! That’s a bit beyond my skill set … but I’ll give it a try …. Unless someone knows for sure !
