You would be wiser to go for Perko mounts, which are not dependent on rubber alone for holding your engine in. If you have new Yanmar mounts, a bit of chain to stop your engine from breaking loose completely would be a good safety factor.
I agree that Yanmar mounts have no captive design against lateral (rolling) or uplift (capsize) forces. Fortunately the design does allow a quick and simple captive securing, i.e. with a chain.
