How to tell if engine sunk

Hello everyone,, Looking at used 2017 50hp etec. Great price owner says he doesn't like it and just wants to get rid of it... I have trust issues. Runs ok, looks OK. If I bring this to a dealer, and hook it up to the computer, would the diagnostics tell if it was ever submerged? Is there any way to tell it sunk? Any ideas? Advice?

A close inspection by an experienced tech would help. Often a trained eye can spot corrosion inside or behind electrical connectors, discolored B+ areas if the motor was sunk with the battery connected and the switch was ON, if equipped. Removing the oil tank or other parts and looking behind them can give clues as would inspection of the flywheel magnets and stator.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor.

Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
