2001 XP Engine Noise

Sort of need to know where/how to start identifying an engine problem. on my
01 Sea-Doo XP. My engine and compartment is spotless. I keep everything
flushed well too.

Was skiing yesterday doing some tricks in the intercoastal. Tricks means
quick turns, stopping/spinning, don't know all the terms, but a lot of hard
throttle for few seconds at a time. After about 5 - 10 minutes of that I
cruised for a few miles at top speed on smooth water. Turned around to go
other direction, again, ¾ to full top speed. Went through no wake zone, and
then returned to top speed full throttle. After a mile or two, out of the
blue, I hear an abnormal noise from the engine or somewhere. I slow down to
a stop, and the engine goes to idle speed long enough for me to hear all
this clanking noise. Then it died on its own. I got that feeling- you know,
open water, floating with the tide, no cell, dark in two hours. anyway after
going through that agony, I tried to start the engine. It sounded terrible!
A lot of rough noise, and with just a little throttle, much harder noise.
The noise is metallic but sort of like ringing a bell- a deadened bell, but
not a solid hard metal sound. had some tinny sound to it. And another clue
may be the very last sound that I hear every time I turn the motor over- a
really plain squeak. It doesn't squeak as it is making full revolutions or
if it starts, but when it stops- the last little rotation as it is coming to
rest. It will start- but dang; the sound scares me. I flushed it as good as
I could and started the engine long enough to get some circulation of my
salt inhibitor stuff through the flush.

OK. Was in open, what should be clean water as far as shells or weeds. I
didn't see anything. The prop and jet house looks fine. I don't have the
little MPEG diag thing to read the troubleshooting codes- if that is worth
buying let me know. I guess I will start checking the compression next??
Does anyone have any idea where to start other than that?

Sounds like either your pump bearings or something up in there that you
can't see (shell or wood "hidden" in the impeller vanes).
