Possible problems?

I have a 2001 225 ho ficth. the battery compartment was flooded all the way to the top. I drained it and replaced the oil. Several months later took it to the lake for a club event. The night before I put new plugs in it. Started and ran great for a few hours. On a long run I noticed it would not go above 5000 rpms so I headed back closer to the launch ramp. The next time I started it, got an alarm. I shut it off and restarted it. It would not come up on plane. So I idled 2 hours back to the marina and put it on the trailer. The next day I pulled the plugs and #6 had excessive oil and fine metal shavings on it. I checked compression and had aprox. 125 # on 1-5, 6 was 120

Questions
Did the motor go into safe mode?
What could cause the shavings?
What should be my next step?

Thanks Randall

Metal shavings is not good, you have lost a cylinder. Time to pull the head and see how much damage you have.

You won't know what is going on until you hook up the PC. Those comp numbers aren't out of whack. But a read out of the EMM will tell you if you have any codes. Did you follow the recovery procedures for a submerged motor? Even though the motor was not sunk the oil tank sounds like it was.
