The first made for racing outboards sold to the public were made by Caille in 1925. They were opposed twins with piston port intake. What set them apart from the Caille fishing motors was a streamlined lower unit.

Waaaaaaaaaay back to the beginning

Since 1925, about 150 different racing outboards have been made.
The second generation Caille racer had a lower unit that could have the prop mounted on the back in the normal way - or on the front. Here is the prop on front, in the tractor postion

That lower unit on the left was typical of outboards in the 1920's.
This update of the Caille also featured an alternate spark plug location in the end of the cylinder instead of the top ... depending on which you thought worked better.
Caille wasn't the very first to make a smooth fully streamlined lower unit, but it was one of the earliest. In fact, they had stolen the idea from Johnson. Johnson had the patent on lower unit streamlining for high speed (in the 20+ mph range!) outboards. Seems unreal 80 years later that the idea of a smooth streamlined case would help an outboard go faster compared to a clunky bolt together with external flanged case, but in 1923 it wasn't obvious. Ignoring Johnson's patent would come back to haunt Caille in the 1930's.

The next maker to step up making racing outboards was not in the US, but England. Watermota was the name. I'm trying to find my image of the Watermota "Speedmodel". I'll post it when I find it in a few days, along with the specs of the motor.

I drove through Hampton wick this afternoon, sorry I saw no trace of the factory, so I don't think there currently being produced.
