IMHO, you will never get the result you are looking for w/o GOOD mounts. My friend and I built a wood downeast boat a couple years ago, it had a gasoline engine. He insisted that there would be no soft mounts b/c "they don't use them downeast" (which isn't really a reason at all) Anyway he spent two seasons trying to get it quiet enough that you didn't want to jump overboard after an hour or so.
This spring he gave in and we installed Cushyfloat mounts and made it a whole new boat of it. All that he had tried to do b/4 was useless b/c he wouldn't solve the underlying problem, structure borne noise & vibration.

Of course it would have been easier to have installed them in the beginning rather than working in limited space, having to cut the engine beds, and invent new ways to mount things to the engine that were mounted to the beds and stringers. However the end result was worth it.


When on the bridge of the Island Seeker, you can not hear the engine at all. The bow wave is the loudest noise. More restful than a sailboat.
