I am rebuilding an engine on my GSX Seadoo 1996 and noticed a small amount of water seeps through the fiberglass at the bottom of the craft under the gas tank area. The moisture is obviously coming from the area between the fiberglass hull and the outer liner. Is this a problem of concern, and if so what is the recommendation. I noticed there appear to be plugs in the fiberglass bottom that are silicon sealed. Thank you in advance.
