Well, if you have seen my other post you know what the story is, if not here it is.
Picked up a tin boat the other day which someone had hacked a kawi jetski pump into, driven by a sled engine. upon research i discovered the donor jetski was an 87 js300.
Anyways, the thing was pretty sluggish in the water, partly due to a POS sled engine thats on there and partly because of a beat up pump.
Heres a few pics of it tore apart. It appears the impeller took the blunt of the damage, the housing has some minor scarring but nothing huge.
Im thinking of just cleaning up the impeller with a die grinder for now (cant get it much more out of balance than it is now) and throw it back together and try to get the motor running better or a different one on there to see if the pump is even going to do the job.
Are their any sort of RPM/HP limits to these pumps?
Right now with the way the drive setup is rigged it will give me a theoretical 15-16000rpm pump speed when the CVT clutches fully shift out!
