Evinrude Tank

How do i do a tune-up on an outboard motor?

The motor is an older evinrude 140 v4 not sure on the year. This is going to be my first tune up that i have ever done

One of the interesting "marketing" tools for many outboard shops was a "Tune Up Special". In truth since the introduction of fixed jet carburetors and CD ignition systems, there is little to "tune up."

We would routinely change the plugs, and lower unit oil (really just routine maintenance) and put it in the test tank. Check the timing and throttle cam operation. Make sure it ran ok and that was it.

These engines had a bad habit of loosing compression on one cylinder. Most often a ring issue. So, that's a simple compression test. You can do that with the engine still mounted on the boat. It's done by removing one plug at a time and cranking but not starting the engine. You can get a spark checker and connect it to the plug wire to protect the CD ignition. If you have a very low cylinder, you'll need to get it repaired before it fails.

OMC (Evinrude/Johnson). makes a "tune-up in a can". It's really a solvent/oil blend designed to de-carbon the head and free sticking rings. You just follow the instructions on the can. Note this will not fix an engine with cylinder damage.

The service manuals will give you step by step instructions for a "Link-N-Sync" and declining the head. In truth just check out Youtube:
