Re: Engine Mounts
I know that is not your boat. I also know that diesels knock about a lot and need a firm footing, as does any engine.
Rocking like that of the engine on it's bed is not good for the shaft when it is spinning. Either the stuffing box or bearing will begin to wear excessively or both.
The engine needs to be aligned and tightened down with bolts that won't come loose. It may also require using some shims to get the alignment straight and true.
There are threads about doing an engine alignment but in a nutshell it is about getting the dog to line up with it's tail - that is, getting the shaft straight through the bearing and lining up the engine so it meets the shaft squarely in all planes.
Shims, if you need them are usually made of metal (SS) and slide around the mounting bolts under the engine. McMaster-Carr sells them and they are cheap if you know what you need.
