Hi All,
I’ve been making slow progress on this restore. A local member helped me get the cylinders bored out and replaced the wrist pin bearings. I got new gaskets and seals from Dan, and a local shop blasted the entire motor.
This morning I started putting the powerhead back together, and everyting went back where it was supposed to. This motor has a new crankshaft, new wrist pin bearings, new 0.020" oversize pistons, cylinders bored out to match, new gaskets all around, and new top and bottom seals. I used Permatex 51813 and activator between the block halves and OMC BRP sealer on the new gaskets (thanks for the magazine idea it works great). I bought a small torque wrench at Harbor Freight, so everything is torqued to spec. For the screws, I used my Bosch 12V impact wrench to make sure they are all tight.
Thanks again for all the help and information.
Next up is to reassemble the gear box, and then assemble it to the lower unit and powerhead. New paint and decals arrived form North York Marine, and I’ve got a window in March to get into my friends paint booth.
