Sula is SM 140. These are the mounts removed from under the old volvo. I presume originals. They are by Schwartz and googling that and the numbers brings up very little. I am awaiting a reply from Amel after Easter.

The Vetus K50 is noted. Could be the answer but there might be a weight issue. New engine including gear box approx 300 kg plus weight of the top of Cdrive at 50 kg.
