Engine - Gemini 105Mc Performance

Gemini Power - The Westerbeke 30B Diesel Engine

The Gemini is powered by a 27 hp Westerbeke diesel with 55-amp alternator and heat exchanger for hot water. It is designed and built using experience gained in supplying over 1,100 whale boat engines to the United States Navy. The greater piston Bore of the 30B Three delivers more power without sacrificing smooth and quiet operation.

To minimize engine maintenance, the 30B Three is fresh water cooled and equipped with a simple control system. Easy access to all servicing points and a self-bleeding fuel system allows easy installation and routine maintenance.

The engine weighs 274 pounds and drives a lift-able, steer-able outdrive leg from Sillette marine with a large efficient propeller. With this configuration, the Gemini can motor in as little as 20 inches of water and when sailing, the drive leg and prop are pumped up and clear of the water. With no fixed prop in the water, there's little to no drag and nothing to get fouled or bent on trap lines or the bottom.

A seacock with fresh water flush makes winterizing an easy process. The engine compartment is lined with Soundown lead and foam and the engine mounts have been selected for minimum vibration. There are two 18 gallon diesel tanks with fuel shut off and two filters.

The instrument panel contains a tachometer, hour meter, and oil pressure, voltage, and water temperature gauges. The Westerbeke diesel is fresh water cooled with a self-priming fuel system. The average cruising speed under power is 7 knots.
