1912 Waterman C-12

Waterman Home


1912 Waterman model C-12.

It's the first model built by Waterman that did not have the cylinder pointing up vertically.
It has a gear driven magneto and I believe this setup is correct for that motor, as weird as it looks with the gearing above the flywheel.

This one has a George Breeze carburetor on it, which is a desirable piece in itself from a collectors point of view.  The George Breeze carb was only offered on 1911-12 models.

The groove around the circumference of the flywheel rim is not factory.

The water pump was attached to the underside of the powerhead, and was connected by a hose to a brass water pick-up that attached onto the starboard side of the lower unit. This is a set-up that Waterman used only on this motor, and the fact that they reverted to the more common water pump location on the gearfoot for the model C-13 would lead you to believe that the powerhead mounted pump may have been problematic.


None of us have been fortunate enough to run a C-12 Waterman to know one way or the other for sure.

In terms of rarity, other than the 1906 air-cooled Porto motor, the 1912 Waterman C-12 is among the rarest Waterman models to be seen. Only produced for about 6 months, the
C-12 was designed so the powerhead could be used to operate other machinery, resulting in the unusual gas tank mounting.

More about Watermans:

The second photo up above shows a problem that cropped up on this C 12 as well as the 1913 C-13.

The supporting braces of the lower crankcase casting often crack and break. There appears to be evidence of a substantial weld repair on the starboard side brace of this motor.

In 1914, Waterman changed this to a stronger design where the housing completely enclosed the driveshaft and its coupling (image below). These things were also known for having the gas tank support brace broken off of the lower crankcase casting.

From what I've heard, the most likely cause for that breakage was dropping or improperly transporting the motor with it laying on its back.
