My motor ran fine last year and now is going into safe mode, well dying and won’t start up again. It will start right up when you get it home and from cold. I replaced the water pump using the eintire kit once this started and now I realize it didn’t fix it. It’s not too hot and the motor is peeing water like it should. And the old impeller was not too bad at all. So, I have to think it’s some sort of sensor. Any ideas? Thanks for looking and responding.

SAFE mode will do nothing to stop an engine running, so it is not going into SAFE mode if it will not start. Start with the basics, good fuel, good spark and compression. Do not give any throttle when you try and start it and you can check the LED lights are showing on the EMM.

I have seen several 25/30's where the electric fuel pump would run for 5 - 10 minutes then lock up and run again after cooling down. To test, you can run it on the hose until it quits the unplug the fuel pump and use jumper wires to apply 12 volts (observing polarity).

Thanks for the replies everyone.  Sorry I maybe using the wrong terminology in saying SAFE mode, and thanks for pointing that out.  So, it just stops running after about 15 minutes like Rick says.  And it does seem like an electrical/sensor issue to me.  I don't give throttle when starting.  I will check the basics like Huey says and then try the electric fuel pump idea by Rick.

The more and more I read on this I do believe its a VST tank fuel pump problem.  I know of another person with a 25 that has had 2 replaced and finally gave up when it did it again.

If an engine has multiple VST failures the quality of the fuel would come into question. We sell and service alot of 25/30HP and have not needed to replace many of these over the many years they have been around.

Huey, your customers are a lot nicer to their E-TECs than mine are. I've done so many that it's less than a 30 minute job. Yes, most of them are due to water in the fuel, lack of use and sitting up with old fuel in them, or connections on 6 gallon tanks sucking in air.

I think fuel quality has alot to do with it. Even though our fuel down here is not as good as years ago i still think is better than many places in the world even more so when we do not need summer/winter blend fuels. I just checked the records and we have need to buy 8 of these in the years the 25/30HP have been out so less than 1 a year in my end of town. it would be nice to be able to buy the parts individually and we have a good stock pile of parts that we can service them internally if needed.

Huey, makes me wonder what the numbers are for other dealers. I think most of our failures have been motors that aren't used much. We put one on today on an 08 engine that had 1,100 hours on it. May be that your customers run their engines often.

Replaced the VST canister with pump and runs fine for 30min. Previously it would only run for about 10-15 min. I initially ran it with the old VST and sure enough about 10-15 min in it stopped dead after just idling. And I jumped the pump with 12v and nothing happened. So, indeed it was VST. I only use this seasonally and admit that it hadn’t been ran for months. It had new gas, but I plan to be more vigilant and run it on the water more often and not let it sit. I do use the Evinrude fuel treatment. Thanks a ton for the help everyone! Hopefully this sheds some light on someone else’s similar issues.

I would like to see more technician's opinion on the problems with these pumps. We have one local tech that says to run a 50:1 mix of the regular TCW3 oil in all the Etec's. I can see where that could be excessive and cause some of the old "gumming up" problems that we had with carbs. I don't have any data that some oil in the gas helps but we have asked some of our seasonal use customers to run a 200:1 gas oil mix so the fuel pump and injectors don't "sit up" in dry gas. Several have reported that it helped. Again, no hard data but just from my memory, I'd say 30% of our pump failures across the entire Etec line have open circuit codes, 30% and just mechanically locked up and the rest are either noisy and dragging or will run 10-15 minutes and lock up (I assume this is due to a lack of lubrication on the lower shaft bearing/bushing in the pump. Recently Evinrude has asked us a few times to send them 3 of our failed pumps. We have sent 6 so far. I don't know if they are asking other dealers to do the same in order to investigate the problem or if it's just our dealership that has a high failure rate.
