Last sunday i took my cen aqua jet out for a run on the lake and it was cruising around at top speed brilliantly but then the batteries in the servo/receiver etc went dead and it got stuck on full throttle pointing towards the boat house but at the second it turned and shot up an enbankment did a barrel roll. So i ran over and it was spraying hot water everywhere then i grabbed it and pinched the exhaust and Finlay cut the engine. The damage is...scratched hull,smashed propeller,dent in the rudder and the pull start doesn't move. Any ideas on how to fix these problems. Thanks DH-02

Replacing the prop is the easy part, the rest might get ugly. Pull the engine out and see if it is siezed up. You might have bent the prop shaft also when it hit the shore which would be better than frying the engine that could be the reason why you're having problems turning the engine over.
With the plastic rudder, you might be able to sand out the dented area if it isn't too bad.

Ok thanks i'll have a look tommorow.
