It looks a little bit like a Watermota engine I had, I think some engines were made in the states called Waterman which were of a similar design

Hmm.. It looks remarkably two-stroke.
What is the bolt pattern for the jug?

aluminum crankcase, 4 hole flywheel, looks to all the world like a T&M racing engine. T&M called it the model "B" (quotes theirs)
15 inch flywheel is a 10hp, 18 inch flywheel is an 18hp
with the friction clutch, probably an 18hp
if you could get me some measurements like crankshaft diameter and main bearing length I could confirm this.
I'm no expert on marine engines, but I have a catalog.

This is my K2 after restoration , I bought it as a seized up lump, it turns out it wasn't seized up at all , the gap between the flywheel and the base was blocked with dead leaves and rubbish that stopped the engine turning.

The chain behind the flywheel says Waterman !

The right front mount leg is wider than rear and has been broken off or corroded away. I believe that was the mount plate for a magneto .

This Waterman was one of the few models that had that chain driven
magneto.
