Re: Where to get parts for my old rude??
Hi Liam5340,
Well; since iboats is nice enough to host this fantastic forum, a lot of the enthusiasts here are reluctant to suggest a competitor to iboats. From your list above; you should have no problem getting the carb kit, impeller and lower unit screw from iboats. The cowling seal for a 1963? Wow...your guess is as good as mine. E-bay maybe...or one of the salvage yards.
First step if I were you would be to use your motor's model number to start searching for the original OMC part numbers for everything that you need. That will allow you to then figure out what numbers are currently being used for today's parts.
If you post the model number here I can probably give you the part number for that weather-stripping.
Good luck; keep asking questions.

PS: As for making your motor more reliable....you don't mention the condition of the ignition system. The coils on those are usually ripe for replacement if they're original. Most people do it all while they're "in there". (You have to pull the flywheeel....) Replace points, condensors and coils....even the plug wires......
