Dispatch, a 1931 Gar Wood, Fires Her Rolls Royce Merlin Engine

Dispatch does not actually fire until about :55 seconds into the movie. What you hear before that is a 28' Garwood in front of her with a V-12 Scripps Motor. The noise prior to the firing is the oil pressure pump. 

1931 Gar Wood Triple Cockpit Runabout
Gar Wood 33-foot triple cockpit runabouts are considered some of the finest runabouts produced by the famous boatbuilding firm in Marysville, MI. Elegant and powerful, these crafts were offered with either a Scripps V-12 or a Gar Wood Liberty V-12 engine and were capable of exceeding 50 mph.

Manufactured in 1931, the runabout has a 650-horsepower, 12-cylinder Rolls Royce engine. Named Dispatch, she is owned by Tom and Maurine Turner of Carnelian Bay, CA. Her Lake Tahoe berth is next to Turner's Gar Woods Grill and Pier Restaurant.
