Main Engine- 28hp 3GMFCE Yanmar Diesel- Saildrive- Hydralign three-blade feathering prop- Drives 120Amp alternator- Heats fresh water via heat-exchanger

Gen Set- We decided against a Gen Set- Difficult to find room in a 38 foot boat- Few diesel-powered sets available 3 y- Piping fuel to the unit non-trivial- Unnecessary complexity
