Neptune
a Caille motor

Introduced in 1915, the Neptune rowboat motor was Caille's inexpensive motor...it was not a badge motor.
It was available with either battery or magneto ignition.

There was also a canoe version, and a 3 1/2 hp commercial version which I have never seen. They always had a dry exhaust.

Caille Neptune was a straight blade prop (non shifting) version of the Caille Rowboat Motor. The "standard" Caille RBM was a 5-speed. 

As the Caille ads said, "A dandy, low-priced motor for general use.".

Neptunes were sold unpolished as an economy move.

So if you have one don't polish it!

AOMCI MEMBERS,
Your motor could be here!

• company letter concerning Neptunes. This clearly documents the differences between the Cailles early Neptune line and the Caille Branded motors. (And don't confuse this early line of rowboat motors called Neptune with a LATER line of motors called Neptune sold by Montgomery Ward...even though Caille made those motors for MW.
