Jeez didn’t realize how much time has gone by since the post I made. Job hunting occupies my time all day lately with this motor on the side for a break from it.
Took down the entire engine and have found that everything is in really good shape overall with a couple small items needed. It did have a weld on the lower cylinder buried under the years of dirt that I cleaned off. Here’s another question though, the pistons I pulled out have 2 rings at the top like a newer engine would while the ad Gary has posted has the 3 ring pistons which I do have from a 156 Speeditwin project. Does this matter or are the 2 ring pistons okay? I have both after doing some digging in the stash and believe they’ll all work but haven’t checked the dimensions.
Now to my latest question/dilemma, how in the world does the lower unit come apart??? I have the lower cover off and the nose but cannot figure out how anything comes out of there. The forward bearing has no way of pulling it out after removing the large castle nut and the nut on the back side of the drive gear has no access to get at it with any sort of wrench. It’s in great shape but the bearings are making a little noise and I do not want to run it without replacing them.
I’m working on getting some photos uploaded so you can all see the engine since I’ve torn it down and what I’m looking at with the lower unit. For once I managed to pick up an Evinrude with a lower unit that’s near mint internally! Will update photos shortly.
