Re: Mystery Inboard Twinn Engine?

The timer is usually in the front, so the bevel gears would be driving the (missing) timer. That’s a rotary water pump at the back, driven by the straight gears – the petcock would be for priming it. I’ve seen many motors like this with the inspection ports on the sides of the crankcase, but I’ve never seen any with covers on the bypass. And I’ve never seen domed copper water jackets like that.
