Do you recognize what ignition system used this camshaft adapter?
This is on my newly acquired Roberts converted T boat motor. I am guessing it was some type of high tension magneto as the engine did not have a generator (or the T flywheel magneto) If I could find these parts then I would pretty well have everything to restore this correctly.
Perhaps your T boat motor used battery ignition. Was more common, and a timer could have been used to the coils running on battery.
This ad shows another brand T boat engine, and notes the use of Atwater-Kent ignition, which would have been run off a battery. The tall Atwater-Kent timer on the front plate can be easily recognized.
The cam fitted attachment on your boat engine sure looks like an accessory timer rotor.
Here is the Harris Mag Timer, which uses a very similar rotor, for two contacts per rev. Seems like a match to the rotor fitting on your engine.
Certainly these are valid possibilities. Maybe someone will recognize the "rotor" as something they have in hand ( I can hope)
Tried to enhance the ignition setup on the engines in this ad, but still not that clear.
Keyport Boat Works, forerunner of the Kulas Boat Works, was part of the Aeromarine Corp, which manufactured seaplanes and small fast boats for WW 1 support, those same fast boats became useful as "rum-running' boats along the Jersey and New York coast areas during the great experement "Prohibition".
I lived in Keyport, NJ for many years, and the manufacturing buildings stood the test of time until being razed about 5 years ago. Local history.
Delayed memory.... Liberty boats were manufactured at Aeromarine Corp. for WW 1.
That is a considerable help. Mine is the "Model J". I think it says 18 HP which would be about right (consider that a boat engine is always running "UPHILL" (never running light at speed)).
The water pump behind the ignition parts makes it hard to see. Interesting how the bigger engines had generators and starters and even reverse gears.
Anyway it sure looks like a timer "elevator". I do have a KW one of those so maybe this would be a good home for it. I know it has a slightly different arrangement to the camshaft so it is not totally "correct".
I wonder what that carb is?
Here is a little more info that I dug up in Motor Boating mags -
Not sure if the carb, ign, etc. in the chart will match your engine but ???
Interesting; transmission by "Paragon", ignition by Autolite, Carb by Schebler. They had it tuned up to 25-35 hp at 1600 rpm.
Anyway the one I have is the "bare bones" with out starter, generator, or transmission
Looks like maybe I am looking for a Schebler carb and a Autolite distributor.
Thank you for all your help
