just picked up this motor for & 400. thought it was a good deal. the guy who had it was running 50:1 on the oil and he said it still smoked, what am i to use for this year?

Re: 1982 eninrude 7.5

50:1 is the correct mix. You should be using a 2 stroke outboard engine oil that conforms with TCW3 specification.
They often smoke at first but given ashort run at a good speed it should clear.

A synthetc oil may make less smoke and it is an option with a TCW3 oil

These pictures are of my '84 6hp being given its first run of the year in a tank. No smoke there at a fast idle. 10 minutes earlier it was smoking like a goodun though

all 2 strokes smoke, synthetic will help, also doing a decarb will help.

Decarb, take a can of seafoam put 3/4 of it in the gas tank, with only 1 gallon of premixed gas. put the rest in a spray bottle. start the engine, and let it come up to temperature. then remove plugs, and them some real good shot of seafoam into the cylinders, replace plugs, let sit 15 minutes. restart, and spray the rest of the seafoam into the carbs, so the the motor almost stalls, wait and repeat until the seafoam is gone.then take for a wide open spin. then put in new plugs, ad premixed gas to the tank, and take it for a wide open throttle spin. it is going to smoke like a house on fire, during this process.

afterwards compression.recheck

In my second picture, the one with the cover off, you can see the plate with the numbers on the side of the transom bracket.

The model number is also on a core plug on the power head but they are not always there.
