If I remember right the old 4-107 Westerbeke was a U. S. version of the Perkins using the same block but adding junkier periferrals to use in Navy motor whaleboats. The reason for not using the Perkins engine in the Navy boats was that it had to be a "U. S. engine." This might be urban legend but maybe some of the "oldtimers" here can help us out.
regards,

In 1959, a British industrial company, Perkins, introduced the 4-99, a water-cooled diesel engine for general applications, especially power tractors. Perkins, not realizing the marine applications of the 4-99, sold the US import rights to Westerbeke.
In addition to converting the engine for use on sailboats, they also built marine generators from the 4-99.
For several years, Westerbeke had a clear field for exploiting the marine uses of the 4-99 in America. Of note was the solid contract business he developed supplying engines for the 26-foot whaleboats used by the U.S. Navy and lifeboat engines specified by the Coast Guard.
By the mid-1960ís, Perkins took back control and became a fierce competitor offering the Perkins 4-99 for marine use. In 1997, Caterpillar bought Perkins.

Thanks "oldtimer."

Just kidding Gord. I've always appreciated your ability to fill in the gaps of my memory.

Kindest regards,

The Westerbeke 40 = Perkins 4-107. It uses the Perkins block with various differences in accoutraments. We have one (W40) on our Bristol 34. It's was sorely used and abused, but after a little cleanup runs like a champ. Needs a tune-up tho...

The W40 and 4-107 use the same manuals
