If you could plumb steam to the engine you might be able to do this,

There have been a number of successful designs that have accomplished
this goal. You won't get 150hp out of it, but certainly enough power to
move a small skiff at a decent speed- 8hp or so. Traditional boiler
designs are too heavy, but the Serpollet monotube works quite well.
Check out Wally Mounster and Terry William's designs.
