Rudder Broke Off - Didn't hit anything

[BigCity444]

Just a normal day of skiing, skier falls down and instead of power back it powered into it and a hard right turn then zero feeling on the steering wheel. At first I thought it was the steering mechanics but upon further inspection the rudder sheared off. Looking at where the bronze was it looks like rust. Is it possible it was cracked years ago and just now let go with some force?

I do at least one power turn every time I go out.

Anyone know the shaft diameter or know of a parts boat that would have a donor for sale?36052211_10155881955474585_3899872584426061824_n.jpg36177028_10155881955479585_2476760373764554752_n.jpg36088163_10155881955489585_6503558506031874048_n.jpg
