2014 200 Etec HO Overheating

I have a 2014 Etec, E200DHXABB, 5405215. Purchased the boat and motor used 3 months ago. Motor has only 67 hours on it. First couple of times out everything was good. Second time out motor started overheating intermittently and going into safe mode. Third time out anything over an idle was overheating and going into safe mode. Water coming out of tale-tale is scalding hot. Took it in for new impeller kit, thermostats and popit valve, mechanic said that there was a bulletin out on the popit. Took it out yesterday and still have the same issue. I have verified that  water is flowing through both EMM and VST. I have read several posts on other sites and this seems to be an ongoing problem with no resolution. Everyone has replaced the same parts that I have to try and rectify the problem with no resolution. Anyone here have a suggestion or remedy?

Thanks, 
Wes

Re: 2014 200 Etec HO Overheating

Troubleshooting an overheating problem has to be done in the water and systematically.

 

First is to find out what and where the motor is overheating. The diagnostic software reads the error codes stored in the engine's computer - the EMM

 

A restricted flow of water through the EMM heat-sink and the vapor separator tank will trigger an overheat warning and a special error code.

 

An engine block overheat triggers a code that says which cylinderhead and how hot it got and how many times and when.

 

The next step is to determine if it is an actual overheat or a false sensor reading

 

Third is to use a temporary water pressure gauge and run the motor at all speeds to compare pressure readings with the factory specs.

 

Another test is to find out if there is aerated water being ingested due to hull abnormalities, improper mounting of transducers or thru-hull fittings, etc.

 

Troubleshooting of a system is finding how and where  a problem exists. Factory trained technicians are taught these procedures in addition to using a factory service manual and the required special tools and equipment.

***************

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with 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, 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.
