The engine looks like a Lehman 120 to me. Natural aspirated with a CAV fuel system.

Baker:

The engine tops out at about 2,100 rpm, and the black smoke indicates it's definitely overloaded and overfueling. Clearly I don't run 'er at that more than momentarily. The boat doesn't...

On Rise 'n Shine the main sound reducing factor is the propeller - the P.O. "overpropped" the unit so I cruise at 7 knots at 1,400 rpm. It's making around 25 hp, I reckon from the fuel burn (which...
