Hi guys, I'm new at this forum so any help is greatly appreciated. I was riding my 3d and the engine stalled ( no buzzer or warning light) it started again but only for a few seconds. When i got it home the entire exaust was melted. I think i found the reason, the seal that goes from the hull to the jet pump assy had shrunk (the water intake from behind the impellor),am i right? Instead of a new exaust I put a staight through pipe from the muffler to the outlet. It is now harder to start but goes great, am i going to cause any damage by this modification? Thanks heaps. Rick
