Trying to identify age of engine. I haven't been able to find any historical photo's of engine without bolted on exhaust manifold.
Any help would be appreciated. Also looking for muffler.

I believe this engine to be a rare example, possibly one of a kind but the photos need to be better ! 4 photos, front back and sides. photos of the entire engine each shot.
Will try to get as much info as possible !
If trouble posting photos click on my name at left for email address and send, I will post them here.
Cool old T & M like to know more about it ?

Richard, I have one on the shelf, you may have pictures of it. It doesn't have the tower timer, but that may have been modified. If you don't, let me no and I'll get some. It may be a little later, don't remember an oiler port on the intake or the water valve on the exhaust.

The engine came from Michigan and apparently still runs. Still has original black paint. Has numbers '22 V 29' on side of exhaust manifold. What size oiler? I am going to restore to original condition(photo's would help), also looking for a muffler.

J.B. A fading memory is kinda like starting a cranky old engine, they both will still work but it takes a bit more attention !

About 2 yrs ago your T & M was the first of this style to show up !

jbt1


jbt2

Motorcanoes engine is the second known of this style !

The 1904 and earlier Termaat & Monahan marine engines had a solid flywheel, lever timer, and a 4 bolt removable head very similar to the St Lawrence heads ! The big technological change for T & M marine engs was the year 1905, headless, balanced spoked flywheels, the large bolt on condenser, two port intake manifolds with poppet valves, and the tower type timers.

1905

t05

More info is needed about these two engs but so far it seems that the condensers were cast with the cylinder as one piece several yrs earlier on water pumps and generators, this must have been a rather difficult pattern and casting ?
This eng in my collection I believe to be an early pump eng but sure could pass as a marine eng, it has a Rotary intake also designed into the casting, as well as the cooling exhaust condenser.

RT&M

rT&M2

It seems to me that the two engines under discussion here were T & M's first design at a headless marine eng incorporating their ealier technology but found casting the crankcase, cylinder and condenser separately to be more practical ? until more exact info is found these engines I would date as late 1904 to early 1905 ?
Time may tell ?
