  How does the drive work? belt?

Frank, the crank snout has a coupling slid over it and pinned, then prop shaft has matching coupling, in this case its direct drive, no in or out, just turn it off to stop! the vee belt on flywheel is for alternater. Other style front covers have in/out clutch dogs to get nuetral. A pretty common era of boats here.

Bill, Got it.

      There's no reverse then either. There must be 30 different styles of drives, we have some weird ones as well. Most included some form of transmission with a reverse gear. No clutches, just a gear engagement of some form.

And then Hamilton jet drives with reverse done by moving flap that changes the direction of water flow...

My uncle once had a small boat with an inboard putt-putt engine.  You started the engine by spinning the flywheel.  Whichever way you spun it, that's the direction the boat would go.  No clutch, no gearbox.  Maybe it was some kind of old military boat, I was a little kid when he had it.

John, fond memories of those put puts, most little hire boats here had these simple 1 cyl pull start by belt motors, generally reliable until my mate pulled the magneto top off and half apart and lost little part through floorboard of boat! I had a few of these engines, Common one here were Chapman pups, and in 1 & 2 cyls in line etc.

Seppo, cant beat the hamilton jet, I actually have old customer who was racing his Y Block powered hamilton jet flat bottom boat! up till a few years back.!!

yyy

 neat subject! where was this Jet thingie made? That put-put looks neat too, it's fabricated water jacket looks like a piece of pipe! I have seen something similar to what John described, it was on a work boat used to repair docks and wharfs. Sounded like a John Deere, swimming

One or two cylinder boat engines were manufactured in British Columbia years ago, by a company called "East Hope". They were often found in Gill Netters.

Frank, the hamilton jet were from New Zealand and sporned the flat bottomed drag style boats that race around a really tight and twisting man made coures in only a foot or so of water, they have a navigator that just points at upcoming turns, theses are blown alcohol boats with big rollbars and hitting the banks and rolling over is just as common as race car spinning out. they race the clock.
