I have a 2009 35hp longtail. Yesterday after taking it out for an afternoon hunt my motor is knocking really bad. It's never happened before like this. Before it started knocking the motor just died all of a sudden while driving and then when I got the motor to start again it just started knocking really bad. Sounded like someone was hitting it with a metal hammer!!! I also noticed that the two bottom bracket holding the exhaust is crack on both sides!

Does anyone know what might be wrong with my motor? Also what I can check in order to get this fixed?

Also if anyone here knows how to fix it PM ME PLEASE!!!

I'm located in MN.

Anything will help!
