Normally the Elto’s of that era used step-cut piston rings that were pinned. Crankcases evolved as production proceeded through 1928 but refer to this image here for more thorough info regarding which crankcase was used on which motor.

On page 5 here, you can see the codes assigned to each motor. You’re going to want to pay attention to codes #7 and #10 with regard to whether a given part belongs on your motor or not.

This one has info on part numbers for other powerhead parts

The reason for changes in the oil grooves could be numerous. If the factory changed anything in the production of these motors, they did so because it was an engineering improvement. Ole Evinrude was reputed to be very diligent in insisting that when motor quality issues came up that something be done about it and changes were often made on the fly.
To remove the tiller handle bracket bolts, they often have splines on them that get stuck to the bores they fit into, so some persuasion may be necessary with MAPS gas torch heat and a brass mallet to get them mobile.Obviously they have to be pushed into the centre and don’t try getting either one of them out if the other one is partially dislodged because you need every centimetre of space in that area to get them completely out of the crankcase casting webs.
Hope this helps.
Best,

April 10, 2026 at 3:38 pm #314923With regard to my post above, I use this booklet a lot when there are questions about what belongs on Elto motors built in the 1921-33 time frame. If you can get a copy of it, I urge you to do so. Over 120 pages of useful information is in it.

These clips are from a long deleted “Boathouse Repair ” video from back in the olden days when a drill had a cord attached to em,. Its easy to do with tools most everyone would have and doesn’t cost hardly anything. I wouldn’t use vice grips on the tubing today. Just spin it in the drill to cut it. https://youtu.be/5fA2fwN0Sgo
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

April 12, 2026 at 12:44 pm #315158One of the flywheels has a stuck knob-currently soaking that one with a penetrant.
the other one came with an aftermarket (?) knob/spring which is not installed. It looks like the pin with the slot goes into the sleeve and seats in the hole in the top of the knob. Does the tip of that pin just get peened to make it all secure?
Thanks for any insight!

Yep. That’s way they’re put together. I can’t imagine what the slot in the pin was for. Maybe had something to do with the process of making the pin.

Correcting that now, I will re-add that scan once I correct it…Thanks for the heads up Chris
