The Gray Motor Company
Stationary Engine Page
Hello, I'm Tom Green from north central Minnesota
This web page is for "Hit and Miss" engine enthusiast looking for,
and willing to share information on GRAY engines built originally by the Gray Motor Company
in Detroit, Michigan, as early as 1906.
Later on, many GRAY engines were either built by, or sold by the "Termaat and Monahan Company"
in Oshkosh, Wisconsin. and some by the "Nelson Brothers Company" in Saginaw, Michigan.
The Gray Motor Company also had a marine engine division, which they were well noted for.
I'm told that the Chrysler Corporation bought out the marine division of the Gray Motor Company.
See "TIDBITS" below for more information on the GRAY Motor Company and their engines
My interest developed in the GRAY engines with the purchase in May, 2003,
of my first and only "Hit and Miss" engine....... to date!
It's a GRAY, 2 1/2 horse power engine. After buying the GRAY engine,
I naturally set out to learn more about their engines and the company, but soon found out
that the GRAY engines, and information on the same, are few and far between.
Thanks to some fellow GRAY owners and other lovers of old iron, some of the pieces are
starting to come together, but the puzzle is not complete yet!
That's the reason for this web site..... to gather and post information on the GRAY engines,
to learn, share, and have some fun!
Please submit your Gray engine, company tidbits, photos and other related Gray engine
information to me at tomfg@means.net
I will add your information to this web site. Let the fun begin!

It's a "Not a GRAY" - "GRAY badged" engine,
I think!
Bill Miller seen this engine at the Portland Show.
It appears that someone put a "GRAY" brass tag
on this fancy looking engine, in lou of it's original tag.
This engine was posted on SmokStak, where
someone believes that it could have beginnings
as a 2hp throttle governed Witte.
If anyone knows the truth behind this engine, Please let me know!
Anyone know the owners
of these fine GRAY engines?
