I'm a newbie to antique outboards and was recommended to this sight by an AOMCI member, Travis.
I recently completed building a Glen L Squirt http://boatbuilders.glen-l.com/squirt-design/nggallery/squirt-design/Squirt-built-by-Jim-Young,-Brighton-MI
and I'm powering it with a 1957 Johnson 18hp FDE-11. I bought the motor before I started on the boat, and a friend helped me get it running. It starts easily, runs fine, and looks good on a mahogany runabout. I am in the middle of restoring the motor mechanically and cosmetically, and have a few questions...
I have the motor torn down, and have identified most of the parts/gaskets I need and ordered them from Dan in TN. The motor has 115psi compression in each cylinder, and there is no scoring of the pistons. So, I hope to not have to crack open the crankcase. The coils were replaced by the previous owner, but the plate is covered in oil, so the top seal will be replaced.
First questions, I removed the top oil seal and noticed some black areas on the crankshaft. I thought this was just the disintegrated seal, but it is pitting of the crankshaft under the seal. Can I get by without replacing the crankshaft, or is there a way to repair it? Will the new seal last if I don't? I checked the bottom of the crankshaft, and the carbon seal is fine, but the internal quadrant ring will need to be replaced, and there is no sign of rust.
Next when I removed the power head from the lower unit, there is no baffle plate (P/N 0304589). According to the parts diagrams, there should be a plate between 2 identical gaskets. Do I need this plate for this motor? I searched around here and on other OMC motors it looks like this may not be necessary. Is this true for the FDE-11s?
After using the motor a few months this year, the gear case was full of water. So, this will be rebuilt with new seals. The forward brass bearing and drive gear bearing are black with some "corrosion." Is this a concern, should I attempt to remove it?
I think the gear case would be easier to prep and repaint the gear case if it was one piece, so I want to reassemble it prior to media blasting it. If it is assembled without oil (so it doesn't leak out the water pump while painting) should I grease up the internals to keep them from rusting? If so, with what?
The carb is in good shape, but I have ordered a rebuild kit anyway. Fuel lines have been replaced. Pretty much all gaskets and seal will be replaced. I have access to a paint booth, so I'm looking at NY Marine or EffenA paints. I'm leaning toward NY Marine since they also carry decals, grommets, and I like the idea of single stage paint. Any comments here?
I am looking for the following parts, if anyone out there has them let me know the price:
376837 (Steering Handle, mine is cracked)
0303842 (Thrust Washer at bottom of pivot column)
0304589 (Baffle if it is necessary)
0304070 (1 screw for gear case (1/4-20 x 7/8", with integral washer) was damaged during disassembly)
Thanks in advance for any and all help and advice.
