Hello everybody,got a few neewb questions.Where can I get info and pictures of the workings of the waterpump,impeller,nozzles,etc.I'm fairly familiarized with the engines.Right now I don't have a PWC of my own but been wrenching on a buddy's one.Most of it repair work involving welding and machining stripped driveshafts.Right now I'm into modifying exit nozzles and need some info on it's workings.Thanks in advance for any info.
