Chris, late reply I know....
Our setup is probably similar, with a largish diesel
(96HP) hard mounted to the engine beds. I was surprised by this but when I finally got to talking to the guy who did the original installation
he explained that he chose that system for the reliability
it provided. He believed it was important in the case of a rope
fouling the prop or should the boat get rolled, and he knew his stuff so I believe these are valid design choices. Similar views were expressed by CF members when I first asked about this setup a year ago.
HOWEVER, despite his good reasons for choosing this method, I am actually going to retro fit our boat with soft engine mounts, as I really have had enough of the noise
and vibration. A 96HP four pot is NOT a smooth device and I have got to the point of dreading using the engine.
As stated above, I believe you would need to check compatibility along the entire drive train, from shaft coupling, to front shaft seal
, and, from my reading, even the rear seal/bearing setup. Our setup with a PSS Shaft seal, a Polyflex shaft coupling and cutlass bearing seems to be reasonably compatible with soft engine mounts, but I have much more reading and phoning around to do before I am comfortable that is the case. I intend to pull the engine this year (no small task) to replace ALL of the hoses so I will do the engine mounts at the same time.
I would be interested to hear what you have decided to do.
