The Marine Engine of the Future

From fishing in a lake to cruising a canal, boating is meant for enjoyment, relaxation and taking in the beautiful environment around us. SDGroup's novel propulsion technology will run on propane, be non-polluting and silent, like an electric engine, yet operate 30 times longer with no recharging hassels.

SDGroup is developing a quiet, pollution free, fuel flexible engine based on an advanced Rankine cycle.
We believe this patent pending propulsion system will be the 21st Century "go to" technology for environmentally responsible boating enthusiasts.
