1999 Silverton. Twin 502 straight shaft inboards. Dewi terized today. Boat runs smoothly at all speeds. But while underway I went into the engine room. The right engine seems to have a very light vibration. You can just barely notice it. The port engine is just rock solid. Is this an engine mount issue. Could they be tightened? Boat was pulled last Spring for paint. Everything was fine then. This is the first time I have noticed this. Thanks.

Put your fingers on any part of a mount/connection between the engine and hull. Bell housing, too. You can feel if something isn't tight. Then get a stethescope to listen for noise coming from the engine. You can use a length of hose or long screwdriver and put the end to any part of the engine. You'll hear buzzing and clicking but knocking could indicate something is getting worn
When was the last time your engines had a full tuneup, with replacement of any deteriorated items ? Engine ignition scan and power balance test?
When was the last time you had the props scanned and checked for play at the cutlass bearing?
When was the last time alignment was checked at the coupler? A strut could have been slightly bent at some point.
Adding to Gregory S's comment, check the engine mount lags into the stringers as leaked coolant or water sometimes migrates into the lag holes and rots the stringer around the lag so they cannot be torqued .
You could check strut to hull fasteners too just in case.
