The EMM cannot sense water pressure. If that is what the tech told you, then it's time for someone qualified who can check it out for you.
Call Evinrude Customer Service with the serial number at 262-884-5993 as soon as you can during regular business hours and explain your situation.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. If you elect to do it yourself, be sure to use caution, common sense, and to observe all safety procedures in the vicinity of gasoline, moving engine parts, high temperature components, heavy items, and electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, correct tools, and have an understanding of how to proceed with a repair. If you are unsure or uncomfortable with a procedure, a situation or a technique, enlist the services of a factory trained technician.
