Cavitation if debris is located behind impeller not in front of???

[Fasman]

HI guys love the info here...its as good as snowest.com the snowmobile site...I jus bought a Tigershark 640 daytona and tho it will get up with smaller kids...I am 275 it takes a bit to plane off and when you spin out on it the thing whizzes as it cavitates..<br /><br />I read on here about the causes and things to check for...I looked at the wear ring and it is very close tolerance...The impeller does have a few nicks tho nothing major... the intake is razor sharp almost<br />The only thing I say was pine needles located behind the impeller too far into the nozzle to get out so I will have to remove the rear portion to get at them... I think they got there over the winter not ingested...there are by sight 10 or so stuck in there... would this cause the problem I am talking about<br />Once it gets out of the hole it is a screamer...tho porpisess alot... that will be my next topic

I got out all of the pine needles and again the wear ring looks to have a very close tolerance...<br /><br />I noticed that the 6 peice pie shaped outlet before it gets to the nozzle has been melted right behind the leading edges where the water boiled and melted the aluminuim.<br /><br />Taking it to the lake to try it out...something tells me its not the answer....maybe I will call Jeff W
