On your transom...
What are the deminsions on the back plate?
Mine is so far from orginal, not sure if close to right size.
May not remake before April, but want to be ready if time.
Finally off for a weekend and it looks wet and cold.

OK, Mine is 15 1/4" across the bottom, and 19 1/4" across the top, with a 14" height.... before you cut it, though, be sure to make the diagonal edge lines up with the bolt line, or it'll look weird.
removing the lower unit.... is there a trick to it? I removed the large bolt on top, and the 6 underneath, but it's stuck. It drops about 1/2" then no more. I didn't want to force anything, since it IS a 50 year old motor... suggestions?
The cylinders are soaking in WD40, too.... SOMETHING'S gotta give!
jp if it is a johnson there is a insp plate on the side of shaft housing about 1 to 2 inches long 2 screws remove and loosen shift coupler should let lower unit drop i hope you dont need any parts but i have at parts motor
Here it is, test fitted. The inner board is in there to stay, the outer needs to be removed later today so I can re-rivet on the transom brace, then I can put in all the stainless hardware and call this job DONE!
I also need to remove the handles and give them a good buffing on the bench tool before installing them and tightening everything up. I also need to make one more mounting clamp for the pick up tube and get that in there, then it's floorboard time! I'm thinking about just putting a piece of ply in the back for now, stained and sealed to match the transom. Maybe later I'll laminate some T&G flooring to it.
OK, the cylinders have been soaking in WD40 for 2 days, and I got the lower unit off, no change, it's still stuck. What's the next step? removing the pull cord assembly and head? Keep in mind, I've NEVER worked on a boat motor before! So I have NO clue what to expect here!

At this point the only moving parts left are the flywheel (it could hang on the stator), the crank, the rods (2x) and pistons (2x). Unless some has a better idea, I would start looking to see if a replacment headgasket is available in your area...it's time to pull the head off and see what's got it hung. The other option is to pull the flywheel but I've never seen one hang and it does take a special puller.
BTW, I learned to ski behind a 14' flat bottom with a 35 hp johnson that we assembled from a box of parts (and no assembly manual). At full throttle the operator had no steering control. Turning the wheel just made the boat go sideways in the original direction

The starter is definitely free. I'll look into the head gasket and tearing it all down. man, how frustrating!
MC, I know that not too long ago I could still get all of the gaskets, seals and coils for my 1953 Johnson 10 horse from the dealer. I also was able to get a water pump as well. Don't forget to replace it. It is in the lower unit, on top.
2 more quick checks. The charging system (stator) is under the flywheel and includes the ignition timing controls. When you advance the throttle, this entire assembly (Lower red arrow on the sketch is the lever) under the flywheel rotates and advances the timing. See if it does this or if it's hung to the flywheel (real long shot). It's possible something got sucked into the charge magnets and has jammed the flywheel.
Second thing. The motors have a detent that grabs the flywheel so you can't pull start them if they are in gear. The upper red arrow points at that, check and make sure it hasn't gotten bent and is engaged.
After that, I am out of clues.
I had a pair of late '50's, early '60's V4's on a 40' houseboat so I spent my time wrenching on these things

Good Luck !
Cool, Thanks! I found a set on eBay for a 58-59. I might go ahead and get them, even though I have a 57. Surely they'd fit?

Can you repost your sketch? It didn't show up. I'm all for figuring this out this weekend!
