1998 24' Wellcraft Coastal

Hi All,
Need some hull information if possible. Since buying the boat a couple years ago I noticed the bow always sits heavy. The engineer did a full boat inspection and did not find any major issues with the boat just stuff he recommended to make better.

The boat is in the water all summer from June to October then on a trailer with shrink wrap the rest of the time.
Last week we spun a hub on the prop. As we traveled in to the dock noticed the bow real heavy. Looked in the cabin at the dock had 5-6 inches of water in it. I then found out my bilge pump had issues (murphy's Law) and was not working on automatic or manual. We fixed that problem but I am concerned about the water in the bow? And how and why it went forward.

So I need a few answers and hope someone here can point me in the right direction.
1. The bow is completely sealed. Does anyone know if the bow is filled with foam? And if so is it a water proof foam or will it retain water?
2.The hull appeared to be in good condition when I purchased the boat. Before painting the bottom I always inspect and have found no issues. I only have 1 thru hull fitting for the wash down and bait well. That area is completely dry. There are a couple of transom mounts for the fish finders. Anyone have any ideas what to check and how to do it?

If anyone can recommend a reputable boat (hull) mechanic please let me know.

Thanks for any information

Don
