Hi all from New Zealand Almost Coronaviris free! I have a luges 320 open running Yanmar 315hp diesels. I’ve had a few issues with leaking shaft glands (I have “drip less’” seals installed). Anyway, I’m replacing the seals on the prop shafts for the third time. My engineering company is saying that the original Yanmar RUBBER engine mounts are not good enough for the job. My engines are pretty new - just 400 hours Any thoughts?
