I have a slightly bothersome rattle on idle when I'm on the water. It sounds like it's coming from the starboard/stern corner. When under way at higher RPM, it sounds just fine. There doesn't seem to be any major cavitation, since I get up to 52 mph.
When the boat is on the trailer and I start the engines, there is a loud rattle from both of them, which is loudest in the jet nozzle area. The starboard engine is worse. If I rev up it sounds terrible. There's no debris in there. The shafts don't have any play on them when tugging on them through the cleanouts. I have never pulled the jet pumps and didn't feel like getting into that today.
Sounds like swollen wear rings, correct? Is there any further diagnostics I can do without starting to pull things apart? There's no way to turn them impeller to see if it's catching without pulling the whole shaft out, correct?

Thanks!
