What's in the registry

Of the boats in the Owners Registry whose owners list an engine, about half have an outboard. Most Grampian 23s and 26s were built for one, many in a well. The inboards, as of November 2026:

Engine	Boats	Most often in
Universal Atomic 4 (gasoline)	45	Grampian 30, 26, and 28
Volvo Penta (diesel)	31	Grampian 28 and 30
Yanmar (diesel)	26	Grampian 30, 26, and 28
Isuzu, Palmer, Universal diesel, Westerbeke, Perkins, and others	about 30	Grampian 30, 2-34, and 34

Is your boat's engine missing or out of date? Update your registry entry, and it helps everyone see what Grampians run on.
