Has anyone fitted Yanmar engine mounts from parts4engines I noticed that the rear saildrive mount is marked 50, however the spec in my manual states that the rear one should be 230. The front ones are marked 100 which is correct. This seems quite a difference.Just wondering if anyone has had problems or if it's ok or should I return it?

I think there is a problem with the figure in your manual. I understand that the figure is the Shore hardness of the elastomer. Shore A scale is 0 - 100 but the upper figure is barely elastic at all, e.g. skateboard wheels. The Durometer scale does not go to 230.

I am finding links to Yanmar mounts that show #100, Shore hardness 50, #75, Shore hardness 40. It seems that Yanmar specify the load in kg that the mount is designed for. I cannot find a 230 but the Shore hardness of the #200 is 70.
