cavitation in a sportster 02 130hp boat

[jezza93]

the bash plate broke and a big rock got jamed in the impeller and made all the edges flat.. would this make it cavit ??

or could one of the drive shaft ends be stripped and make this happen

Going Nowhere? Tolerance between the prop and its wear ring wall should be
.008 as Good, .040 as being Bad. You need to remove the steering nozzel to see
that. Remove the PTO plastic cover to see the pto and the drive shaft. Mark
or paint a line, inline, on each. After engine run, turn off and check that alignment.
This will tell you if the internal splines in PTO are damaged. Then fix one or
all three. PTO, drive shaft, jetpump. Hopes this helps.
