I have an 1989 30 ft Searay weekender. While working in the bilge I kicked the starboard muffler and it came loose. They are kind of round so I pressed it down and didn't think anything of it. I put it in the water and noticed water around the bottom (wet). It this a major problem to change it the water or do I have to pull it.

Many mufflers are at least partially below the waterline and yours probably has a 3 1/2 to 4 in exhaust hose leading to the exhaust outlet. If seawater had open access there it could sink your boat surprisingly quickly. But , you could conceivably seal the transom exhaust ports with expandable plumbing pressure test plugs or similar.
Most but not all f/g mufflers have a screw in drain plug either on the lowest bottom or lower end. You might check to see if the problem is simply the plug got dislodged and could be resealed, but the hose flanges or other f/g may have been cracked.

Sandy +1. Pix would help. I believe the mufflers you are referring to are Vernalifts. Unless it's the plug, you may need to replace it. Off the top of my head, I cannot think of any way to seal it.

F/G mufflers that have not been internally damaged by backfire or extreme overheat due to lack of RW cooling in the exhaust stream can have minor cracks repaired with proper f/g mat and resin layup , but NOT just with resin.
