40 year old outboard never been started
I just acquired a 5 HP outboard from the 70's that has never been started. It is brand new just a bit out of date, not even a drop of fuel was put through the tank. Before I put it on the dingy and give it a go is there anything I should do to it, assuming any lubricants from the factory are long dried up.

do you have a separate gas tank?
Take the plugs out and squirt lots of oil in, and spin the engine, and repeat. I would maybe just hook up the carb and give it a try after a lot of oil. The float might stick, open or closed. Check for spark while the plugs are out. Those coils deteriorate over time. change the lower unit oil. Run it in a tank first. Use a lot of oil in the gas mix at first. what engine is it specifically? |

Sounds like quite the find! How heavy is it?
Not knowing how the engine was stored, changing the lower unit lube is not a bad idea. If it has a real water pump, you should also treat it to a new impeller. You can also remove the propeller, fasten the engine to a saw horse, and stick the lower end in a trash barrel to run it. |

oh yeah, the water pump will be shot. Impeller anyway.
A couple vanes will have a permanent set, but the others may push the water. |

If you plan on using the original tank put ~1 quart of gas in it and slosh it around then pour it out to be sure there is no rust or what have you in it.

Be sure and replace all the fuel lines with ones rated A1 to withstand the ethanol now in gas. The ones in there are most definitely NOT alcohol-rated!

I have lots of experience with motors of this vintage. I strongly concur on:
1. Water pump impeller 2. Rubber fuel lines 3. Inspect fuel tank 4. Replace lower unit lube. Let me add: 5. Inspect coils. OMC motors and some others with epoxy covered coils sometimes fail due to age. The epoxy will fail first and the coil may even provide spark, but if you see cracks or epoxy flaking off, replace the coil. No matter how good the spark it will fail VERY soon. 5.5 Clean points if it has breaker point ignition. 6. Carb float and gas tank guage float. Many 1970's floats are cork with a varnish or shellac covering of some kind. I usually replace with a new plastic float, but sometimes paint the old floats with superglue or model airplane dope. At any rate, the float covering will dissolve in modern gas and the float will stop floating, causing it to flood the engine. Break IN: Follow the manufacturer's recommendations. DO NOT use synthetic two stroke oil, it is too slippery and the rings will not set properly. However, I recommend switching to full synthetic after the break in period.
