Broken through hull fitting

Went out today for our first trip on the lake. While at the launch ramp I noticed the bilge pump working overtime. A quick inspection found the port through hull fitting for the deck drain broke and water was rushing in. Pulled the boat out. The through hull plastic fitting cracked and broke in two right on the inside hull surface. The fitting was clearly brittle.

I have a 1986 V20.

I will get it fixed this week.

Anyone ever had this experience???
