Shortly I have recognized that my shaft is aproximately 5cm shifted from centerline to portside. As I understand that this could be a design reason I only wonder why it is to portside. All internet sources mention that according to standard it should be shifted to starboard. I have a standard Yanmar 4JH4AE with KM35P gearbox RH. You can also see that the centerline on the hull has a defined angle before the shaft, so it is not a later modification (see picture looking from stern to front). Does anyone can explain this?
