There’s several YouTube videos on the subject of timing and tuning up
OMC vintage outboards. Some special tools suggested, but
not absolute necessary, but they can optimize you best chance
for a slow idle.Prepare to be boarded!

Hi Mike
How much outboard experience have you had? Why is it that you feel the seals in your gearcase need to be replaced? The ignition work isn’t that difficult, but a few specialty tools are required. Setting the points/timing with an ohm meter is not an absolute must, usually the points can be set to .020″ on the highest part of the cam lobe.
There is an inspection cover on top of your flywheel that is easily removed. Once it is off, you can peak inside to see if your coils are cracked/damaged/not usable.
Do you have any pictures of your engine, sometimes it is easier for us to help with the aid of some photos.
Nonetheless, before you begin, you should really watch some videos on the service procedures you would like to perform…
Generally speaking, in order to make your engine a “reliable daily runner”, you should plan on doing the following work
Service ignition system, which may involve replacing the coils, removing the mag plate to replace spark plug wires.
Service fuel system, which means pulling the carb apart to inspect and clean it, reassemble with new OEM rebuild kit, inspect and replace old fuel lines… Your 59 engine came with a dual line fuel tank, do you have it? You better have a look inside the tank to check for rust or crud, the tank isn’t serviceable if it is messed up/fouled inside. You can convert this engine to a single line system fairly easily, but it will require a fuel pump and one intake bypass cover with the fuel pump mounting.
Remove gearcase, drain and inspect gear lube, replace water pump (please use OEM components). If gear lube is milky or has raw water present, then you will need to pressure test to pinpoint the actual trouble area. Pulling the gearcase apart is not real difficult, but removing and replacing those seals can be a challenge. Delicate aluminum castings are easily damaged.
Please ask any questions you have after watching and reading about these service procedures.

I agree with CK, that’s how I learn the best too. As mentioned, videos and pictures help, as well as having it explained really well and thoroughly like some of the guys here do. And it doesn’t hurt to familiarize yourself with what the Service Manual says either. Here’s a link (good for a week) to download a few of the chapters.
When you click on the link you’ll see an option that says “Preview” and you’ll see each individual chapter that you can download as a separate file. Or if you click the blue oval “Download” button it will download all as a “Zip” file that will need to be “Unzipped” or each file “Extracted”…do whatever you’re more comfortable with.

Those manuals look very interesting, anyway to download them?
