Re: 225 e-tec overheating

What are the water pressures at 1000 rpm intervals from idle to full throttle?

We can compare that to the factory specs. Also keep in mind that if the twin engines are not in proper alignment, it can affect water pressure.

Re: 225 e-tec overheating

i have 2006 225 etcs for the first time the starboard motor shut down with over heating message

water was pumping as usual but temp on screen reached 250

Im hoping there is a computer issue as each time I checked the guages the temp rose even though cowling was off and engine off for hours , final temp reading was 280 . The engine was not even hot to the touch. Any ideas from you folks.

I checked the thermostats and they were clean with no build up of any kind. I dont know if there is an overide for the stop mode. Any help is appreciated.

Re: 225 e-tec overheating

Your engine is 8 years old so it should have had at least 2 water pump kits installed and you are getting due for the 3rd. Most overheats are from a lack of water pressure or aerated cooling water being ingested.

 

Your dealer has the factory charts for water pressure readings at various rpms and the motor should be checked for correct readings first. A gauge can be temporarily hooked up for testing purposes

Re: 225 e-tec overheating

Yes sir the water pumps were installed less than 50 hours ago- havnt had much time to play- change then every 100 hrs

the other motor has been an issue for two years - at idle and less than 1400 rpm the temp climbs up to 200, as soon as you increase rpm the temp drops back down

both motors run within 15 degrees of each other in cruise mode. The new issue is with the motor that never gave me an issue. Do you know if the there is a reset on emergency stop or does the tech need to do this

Re: 225 e-tec overheating

The engine will shut down when subjected to a severe overheating condition. There are warnings long before that happens to a shut down code could be construed as neglect is certain situations.

 

the engine will run again when it cools down enough.

 

Have your water pressures and pressure relief valves checked.

Re: 225 e-tec overheating

I have 2006 etec with 410 hours. This motor has been problematic since day 1. I have a authorized Evinrude shop working on it.

 

We've gone through a dozen 'overheat' alarms at various speeds. Tried different inlets, new waterpump..constant impleeler changes. The computer readout says it's never overheated...just the computer thinks it has. Just spent $2000 on a new computer...second day out running at 1200 rpm with 8psi...buzzer and light came on...went into safe mode.

 

This is hugely frustrating and makes me want to buy ANYTHING but and Evinrude.

 

Total Spend on this issue is over $4000 and it's completely unreliable.

 

Anyone got any suggestions at all?

Re: 225 e-tec overheating

Troubleshooting an overheating problem first has to determine if there is a temperature problem or if there is an erroneous sensor problem setting off the alarm.

 

Some of the early model E-TEC V-6 engines had service bulletins about cooling systems that applied to them depending on their serial numbers.

 

Sometimes overheating can be caused by transducers on the transom, thru-hull fittings in line with the motor(s), or even trim tabs if too close to the engine's water inlets, any of which can disrupt or aerate the water flow.

 

A restriction or lack of flow through the EMM can elevate its internal temperature and give an overheat alarm even though the engine block is cooling correctly.  A clear line  temporarily connected to the EMM would show any aeration if that was the problem. An inspection of the engine report contains the engine's and the EMM's cooling history.

 

Of course the basics have to be covered first such as the correct water pump kit, no exhaust or air getting into the system, no debris in the cooling passageways, thermostats correctly installed and working properly, and the pressure relief valve and internal seal clean and positioned correctly.

 

Your dealer can also take advantage of Evinrude's Dealer Support Hotline for assistance with any hard to find enigne problems. Discuss these items  with your dealer.

Re: 225 e-tec overheating

We have gone through serious fault testing on this motor. We ran the thing extensively with the computer attached to it, while underway. Even went so far as to replace the EMM. As I said, according to the EMM, the motor has never overheated just the EMM. Hence the replacement. The very odd thing is that the motor is still not overheating but the brand-new EMM is. I suppose it's possible that I spent $2000 on a brand-new faulty EMM. Seems quite odd that it's exhibiting exactly the same problems.

Re: 225 e-tec overheating

Can you post a copy of your latest engine history report?
