Default Busted fin

I don’t remember hitting anything but I look at lower housing today and one of the wings above the prop broke off. See pic...
A few questions:
1) how does this happen?
2) can I drive like this for awhile?
3) what part do I need to fix this?
4) how much $$$$?

I love owning a boat sometimes!!!!
Thanks! Mike

It happens, sometimes we never know why. Yes you can operate the boat like this for awhile. You’ll need to find a welder who can work with aluminum to make and weld in a patch to the cavitation plate.

You're going to need to get that fixed. At higher speeds, you might get a little cavitation. That anti-ventilation plate prevents cavitation. Think of using a blender, or a mixing paddle with paint. A vortex is created that sucks down in the center. That is what happens above your prop. That plate prevents it from occurring and ensures that your prop is biting into water and not air.
