15 hp petrol/paraffin outboard with a small electric coil to provide enough juice for a little light which goes on a pole on top.
The "separate" tank has two compartments. 1 small - for petrol (premix) and a larger one for kerosene (premix)
You start and stop it on petrol and once it's warm enough run it on kero.
I rebuilt mine years ago but haven't used it in yonks. I had a manual for it, but wold be hard put to lay my hand on it now.
It is a curio now. It is a bit smelly on kero.
I don't know anyone else who has one.
