I am curious how you managed to install the 200 kg Sabb engine after you built the boat. This would be good information if I ever need to remove the Sabb engine in IDUNA.
As a side note, I moved the two propeller shaft "greasers" from the lazaret to the forward engine access located under the companionway. I accomplished this by purchasing two bulkhead brass fittings that have NPT threads on the inside - see attached image. The two bulkhead fitting were installed in a 90 degree angled bracket. The bracket was then mounted to an engine compartment bulkhead. To grease the shaft, I used a grease gun which I connect to the zerts screwed into the brass bulkhead fittings. Hoses connected to the bulkhead fittings carry the grease to the shaft and prop hub.
