Right side engine running lower RPM's

[T_H_O_P]

While out this weekend I think I may have sucked up some grass into the right side impeller. We were floating in the lake and not really paying attention to where we were. When we decided to move we were in some really thick grass. When i accelerated out I had a really bad vibration on the right side that quickly went away. I stopped and went under to check things out and couldn't find anything stuck. So we continued to boat for the rest of the day. After this happened everything seems to be fine accept at WOT my rpms on the right engine only go up to 6000 they used to run at 7300. I have not lost any speed off the top end, but I seemed to have lost just a little out of the whole.

Any advice would be greatly appriciated. Thanks in advance.

pull/clean the raves, and replace spark plugs.

I changed the plugs and there was no difference. I was thinking the raves but wasn't sure now that u suggested it i will do it. Thanks for your help.
