Just bought a 2018 Trixx with 9 hours on it knowing it needed repairs. Thought it would just be rock damage to ring and impeller as rocks were still there. After that repair and launching it didn't run in water for more than 30 seconds and warnings popped. Now have deck off and see that exhaust coupling and elbow hose are fried, water box is melted at inlet and there is a stray single piece of stainless loose in the muffler rattling around and sensor is melted. I am next going to get parts removed and check for water blockage.
1)How does the water box come off, is it just the big nut? It looks like a rivet is holding it from turning?
2)ever heard of the muffler innerds breaking apart? its a 1X2 inch piece.
3) best way to diagnose cause of all this?
The engine seems fine
Thanks for any help!!
