You should be good with that mix, I worry about using only two stroke oil if the motor is going to sit long before the first startup.

Thank you Ray.
So.... I have been using 105 assembly grease, is this of a good standard?
Also, I was unaware of "bearing grease" untill now.
I already replaced all the needle bearings. I used a mixture of 105 assembly grease and 2 cycle oil to hold all the bearings in place while reassembling. Any thoughts on my concoction?
I was under the impression that the grease was just used for initial start up until the fuel oil mixture kicked in and Lube everything up as normal.


I did use an inch pound torque wrench, with some red threadlocker on the rod bolts. But I do not have any torque specs for the two halves of the Reed cages, I was just going to use threadlocker....

Thanks for all the help.

I don't think that fine will do the job, a light hand with about 320 to start and it may take more course than that, I would wrap the paper around a paint stir stick or something so you are working flat, no need to undercut it but any raised smeared aluminum needs to be took down to no higher than the good material. You don't want the skirts to be polished, they need to be able to hold a little oil. You can dissolve the carbon in the ring grooves with acetone. The rod bolts on these are a little tricky to torque correctly.

I like the bolt layout, I take a lot of photos before and during a tear down like this, especially on these old merc's , they have a lot of moving parts both internally and externally, all the little details can be hard to remember :doh:


It looks like you have some minor scuffing on a piston or two, you will want to take care of that before reassembly.

Looking good there. You will be glad you replaced all you can while it’s apart. And rewarding once it’s back together to know you should have a reliable motor. Nice to have your son involved too.

Thanks John for the more details on how to replace the bearing in the pilot assembly. It was very easy.

I took the assembly all apart and cleaned old grease out. Made sure the zerc fittings still worked then put it all back together.

After my son took everything off the powerhead a few days ago, here is where I am at now.

Cylinder walls look and feel great, Pistons look great too. I will be replacing the rings, all needle bearings and upper and lower main crank bearings and seals, and upgrading to carbon fiber reed valves.

One of the main bearings was shot, glad I got to it now. And a lot of carbon build up behind the exhaust cover.
