What is the battery voltage?
Again, what is it when you crank the engine?
What is the compression of the cylinders?

I agree w/ above.
but anyways Hi & welcome to the forum.

Battery voltage 12.3, voltage at starter 10.6. While turning over the engine hit twice, on the second hit the starter whizzed. Tried again and on the hit starter did it again, after that the engine turned over but no more "hits". This has nothing to do with start stop button I assume but originally I was having trouble with button so I shimmed it in the case, after shimming trouble stopped but now I have this issue. I do not have access to compression tester.
Thanks for your input!

12.3 is fine if it would stay in that area. The fact you are dropping to 10.6 is an issue.
Remove and clean all terminals as dirty connections will act just like a defective battery.
Once they are all cleaned (use sand paper and put it back together with dielectric grease) retest for volts just like you did the first time.
You may have a bad battery or bad starter still. But we need to do this to determine that.
FYI. The MPEM stops work at 10.5 volts. So volts are IMPORTANT as are amps as they provide the force behind the volts.

I agree with Joe. Most all starting problems are bad batteries.
OK guys, slight charge on battery put me 11v to starter and engine ran. Will further charge battery and maybe even replace. Although I did replace it at the beginning of last summer and had it disconnected through the winter. So I guess if 10.5 is the cut off for the MPEM it
will not give input to system even with starter turning motor?
Thanks again for your help..guess I will need to take a few Tech courses if I am gonna keep my RXTs
Run them exclusively in salt water although low hours. Am very careful to rinse/flush and use of lubricant on componants but these skis do not hold up well in the salt environment. Sea Doo would well serve its customers as to improving their corossion protection program.

An electric motor is less vulnerable to low volts AS LONG AS the connections are excellent. Electronics are much more vulnerable. Such as the MPEM. Officially, 10.5 volts is a general average where it basically shuts off. So yes, the engine will crank if you have a good starter but the brain will not allow for spark and fuel injection out puts ect ect...
Based on the various readings you have gotten from the battery I am betting it is trash. You MIGHT get through the season but it is on its way out I'm thinkin...
