Scary Leak

So this weekend we were having a great sail.  Clean bottom, tunned rig, 7.5 kts. with a good breeze.  We checked the bilge and found a great deal of water splashing all over the place.  We took all the appropriate measures and located the leak.  The inboard side of the through hole for the scuppers in the back of the transome had cracked off and the opening was open to the seas.  Plugged it temporarily with a wooden plug and we controled the water level and the leak going forward.

With all the stuff I keep in these aft lockers the way the conections are set up are just asking for trouble if redone the same way.  With our open transome is there any purpose to these scuppers?  I'm tempeted to just seal off the opening and the scuppers and I will feel more secure it won't happen again.

Thoughts?  If I do seal them what is the best way to do it?

We have a MkI, so can't offer any personal recommendations.   However, I recall that a former Commodore with MkII  of similar vintage had a similar problem.

Thank you.  Very helpful.  I think I will plug it up.  Any suggestions from someone on good approaches?

I think the scuppers on the MK II are positioned to drain the "T" area of cockpit when  the boat is heeled. The transom through hull fittings are Nylon which degrades with UV exposure. You might also want to check the anchor well drain. On most boats the through hull is located just above the water line and is also prone  to failure. I replaced ours with a Stainless through hull. You have to remove some trim and the V- Berth bulkhead to access- it's a very tight area to work in to access the anchor through hull.
