I would think it’s the same reason as a 2s bike/quad, a little lighter less complicated engine. As Slydog mentioned, they were used in WWII tanks, great marine engine, still used in marine. Here’s a “little” one

Jesus, the redline is 120RPM...that's like watching your favorite 33 1/2RPM record go around the turntable at 3x.

I loved watching these
Rolling Coal coming out of the corners

That V10 TDI was an interesting engine for sure.
I had to replace at turbo on one...once on a Touareg V10 TDI. Essentially, you have to remove the damn engine to do it. In order to do that, you need a bunch of special tools, one of which is an electric table that supports roughly 2500lbs.

I'd love to see how they make these damn things.

Google is your friend ! I’ve see pictures of it (or similar) the journals on the crank are 3feet/3meters in diameter. The connecting rods are two pieces, they pivot in the middle. The ships are literally built around the engine

They are actually more complex than a four stroke to set the overhead.plus with a. 4t you only have to worry about a turbo.2t has a mechanical variable fuel injector .you have to set injector timing on each individual injector along with setting the fuel rack.alot of people don't want to work on them.they don't understand them
