Stuart Sun Engine

Here is the Stuart Sun Engine, developed from the earlier Stuart MTB (180) Engine

Runs smooth !

Two Stuart Sun Engines running on steam, the boat is a Torpedo Boat Destroyer from 1894 called HMS Daring

I've seen it somewhere !

Hello,
Nice installation ! How do you make the reverse ?

Thank you JPA, I am afraid there is no reverse.
The only way would be to make a new gear box, the current gear box links the two engines at 90 degrees to each other. Since the Sun engine is a single acting twin, its possible that it would not self start, linking the two engines creates is the same effect as a 4 cylinder engine, so that it always starts.
No reverse will make life very interesting the day this Torpedo Boat Destroyer finally takes to the water.
