Out at lake for weekend. Surfing then all of a sudden one engine hitting 7200 and other hitting 6000. If I run port engine alone revs till cavitation. Starboard won’t hit 6000? Don’t see anything in propellers, they look in good shape. Any ideas. Removed all ballast and same issue.

Check engine light on? I'd start there and pull codes with a yds.
No engine codes. We docked it for awhile and I grabbed trailer. Wife said she hit over 30 and both engines were equal but was stumbling when coming to load on trailer. If nobody has any ideas I’ll try again this morning.
