Hi.
Sorry but I'm slightly wrong, an article I read stated that the dynamo and water pump were driven from the balance shaft but this is wrong they are crank driven as is normal practice. There is lots of demos on youtube showing the Essex V4 and the Cologne V4 running and it is quite clear that they do run clockwise just like the vast majority of engines, here is one clip https://www.youtube.com/watch?v=YG5Y6sTWTP8&t=174s
It is possible that the engine may for some reason have been modified to run in the opposite direction for marine use but not only would the camshafts have to be re-profiled but the oil pump would need to be replaced with one that would pump in the opposite direction and a distributor set up for the opposite direction too. Using the same distributor would give you vacuum retard instead of advance and whether the centrifugal advance would work I don't know along with static position.
