GRAY Engine Specification Table
This table was created to help people determine what
horse power engine they have.
The data is a accumulation of data from the different
brochures and manuals on the web page, including the
Termaat and Monahan brochures.
There appears to be slight differences of the same horse power
engines from different model years of GRAY and T&M engines,
with regards to the flywheel diameters, and the weights of the
engines, but the "Bore and Stokes" seem to remain the same.
If you find errors, or can add to the information, please let me know!
