I will second what ’57evinrude said! The pre50’s outboards are a machinist dream or sometimes a nightmare but you guys do some incredible stuff! To bring those old timers back to life.

Nice work Mumbles! Don’t expect the same great restoration work
photos from me, lol. I’m amazed those little Thor built motors
ran long enough to wear out!
I haven’t checked out my LU or water pump parts yet.
Any photos of your piston Mumbles?
I’m curious if my .020 over piston is the correct
profile, height, etc.
Thanks.

Prepare to be boarded!

Hi Buccaneer,

What is your serial number of your motor? mine is WK9681

The tiller handle is made from plain 7/8" O.D. steel tubing thick wall .060" -.080" I made mine from a ford tractor mower deck handle!
The spring steel clip with pin mates with a corresponding hole in the tiller handle, the clip is held to the motor with a small machine bolt
And washer to prevent loss etc.
The metal spacer under the rope plate is a factory O.E.M part.
The first picture with what appears to be a grease cup is not mine so I am not sure of this detail/feature? maybe someone with an earlier
Motor can shed some light on that item. I found the picture online while looking for the clip configuration/shape etc…

Mumbles, Thanks for the piston photos. Your’s is similar
in that it has two rings, but mine doesn’t have the
holes in the skirt. Your looked a little gnarly when
taken apart. 😮
When do we get to see it run?

Fifty20One, thanks for the photos. When I cleaned parts this
morning, I see that the tiller retainer spring band wasn’t
riveted on, but rather it was a tit on the band that would
engage a hole in the tiller pipe, as you describe.
Looks like they do have a spacer between the rope pulley and flywheel.
My serial number is WK10783, a little newer than yours I guess.
Started sand blasting some of the parts today.
Didn’t get as much time as I wanted in the garage.
Had a clothes dryer full of wet clothes and it wouldn’t start.
Ended up jumppering the door switch and ordered a new switch.
Awaiting to hear from Otto Engine Works with regards to
"over size" ring availability.
Thanks!

Hi Buccaneer,

I thought because your motor has the angled skeg design that it may be from the first batch of 384 motors returned from
Montgomery Wards. In the book "IRON FIST" chapter 5 (New Directions) the author details how Elmer "Carl" Kiekhaefer
Repaired six enginges using Waterwitch 2.5 HP cranckshafts and coils from the Thor twin to get hotter spark along with
A larger intake manifold and adjustment knob for better fuel control. These outboards were approved by Earnway Edwards
The Montgomery Wards buyer for the Sporting Goods Division in Chicago and he allowed Kiekhaefer to ship the remaining
298 motors back to Montgomery Wards along with a new order for 500 additional motors. A very interesting read IMHO

Attached is a picture of Mr Kiekhaefer (32 years old) in the plant overseeing the repair and shipping of these motors back
To Montgomery Wards for resale.

Another neat photo of the Thors! I thought that I had read "Iron Fist"
at one time. If so, I must have gave it to my uncle to read,
but I sure do not remember seeing those Thors.
I need to take an inventory of the few books I do have……
keep forgetting about them as a reference!

My lower unit stamping appears to be angled, but the angle of the prop
shaft is paralell to the piston. Were some of the early Thor’s prop shafts
angled like a "weedless" lower unit?

Anyone know the "color theme" on the Sea Kings made by Thor, circa 1937?
Mine is painted a light grey, but hard to tell what’s original after 80 years.
