just my .02cts seen this more than once, take the fuel line off the connector to the motor [cut hose] look inside for gunk. our gas eats the liner of the hose and messes things up. won,t hurt and mite show some thing.

 

Go over to www.iboats.com and see it any one else has the same problem.

 

Fuel filter?

 

Is it possible your vent is plugged creating a vacuum?

 

It's possible that your fuel line between the fuel line connection and the fuel intake at the engine is probably plugged due to fuel line collapsing change those lines and the filter. Had a similar problem on a bigger motor.

 

The fuel line, filter, and tank are all new.

 

Even from where it connects at the outboard to the fuel injector?

 

thats where they collect the gunk.

 

Is the vent screw open or closed?

 

I know its a bit of a ride and its also been a few years since ive taken anything there..........hell, the guy might not even be alive anymore. The shop was on the west side of the drawbridge past Port Clinton. Mark Smith was the owner's name. A good guy that loved to talk, but knew Evinrude's well. As you would figure might be a little wait this time of year.
Worth a shot to get dad on the water, if all else fails
Good luck

 

Check the fuel pump pressures, lp should be around 2psi, hp should be 18-20psi

 

There are only 2 types of issues it could be, either spark or fuel. It seems it has to be the fuel since it fires right up.

A friend of mine had a very similar issue. He tried everything; replaced fuel lines, replaced fuel fitters, cleaned carbs, adjusted linkage. Nothing worked. He told me early on that if he disconnected the fuel line from his gas tank and just put the line in a gas can it ran perfectly. I kept telling him the issue was the pick-up tube coming out of his gas tank. There's a screen at the end of the tube and it was probably clogged. After spending 2 weeks of trying everything else, he decided maybe I was right. He tried to remove and replace the tube, but it wouldn't budge so he took a wire and poked some holes in the screen and installed another inline fuel filter. That was it, he took it to the lake, and it ran perfect.
Since the engine is not showing any codes (since its functioning just fine) and the fuel lines have been replaced. I'd look into checking the fuel tank. Even a new tank could have had junk in it causing the screen to clog. If the vent is open and working, I would check the pickup tube. To check it, I would do what my friend did and just insert the fuel line coming from the tank into a gas can. If it runs with no problems, you'll know the issue is with the tank and not the motor.
Good luck with getting it fixed.

 

Have had the primer bulb check valves stick and cause similar issues. Remove fuel hose at carb, pump primer bulb and see what kind of fuel flow you have. Also have had stuff in fuel line on engine, it seems these new fuels can leave residue in lines, I took all fuel lines apart, filters, fuel pump and blew out. Now for winter I remove line at carb and blow all fuel out of line with air hose.

 

www.etecownersgroup.com I found this site years before BRP corp. decided to leave the outboard motor market. Lots of great info from others with etec issues along with etec trained tech people advising. Hope this helps.

 

thats where they collect the gunk.

I'll have him check.

Is the vent screw open or closed?

Open.

 

I have a 30hp etec and found that if the spark plugs aren’t replaced every couple years that it will do this exact thing. Also the spark plugs need to be tightened down so the electrode is aligned so the open end is facing the injector cup. So once replacing where the spark plugs aren’t replaced sets in the head or whatever there is a marking where the injection cup is. Mark the plug where the opened end of the electrode is and try to tighten down so it is aligned within 180 degrees of the injector cup. You can look this up under spark plug alignment for evinrude etec 25hp. I’ve also had issues with overheating before with their garbage impellers that they installed so I do that as well every 2yrs. I use my motor for trolling primarily. The champion plugs are copper ones which cool down faster to prevent pre ignition. Hope this helps

 

Oh also I had the ecu go bad which also caused similar situation but it was more so the motor didn’t want to go. Was told to be sure the battery is fully charged. But sounds more like the spark plugs issue

 

Here is a link that does a better job explaining what I was referring to

 

I'm going to say it's something electrical. Heating up and shutting down until it cools down. I would think fuel pump, but that should have shown a code, likely open electrical circuit at the pump.

 

If the low pressure fuel lift pump or regular fuel pump is seizing after it heats up there won't be a code, the 25hp etec are notorious for the fuel pump doing that, running for 10-20mins and locking up. After sitting they cool off and start working again. Run the engine till it cuts out and pull the fuel line off and try to start it again and see if the pump is putting fuel out to determine this.

 

Appreciate the suggestions by all. I've been sending stuff to Dad for him to check. One would have thought the marina would have done these things as well, but maybe they are at a point where if they don't have a code they don't know where to look?

I'll report back.

Guy just wants to chase some crappie, gills, and saugeyes.

 

Burroughs Marine, Cory will solve your problem. It’s in Clyde OH. 419-547-0651

 

No one has mentioned the possibility of overheating. I had a 15 horse that acted the same way. Finally figured out the impeller was not pumping enough water to keep it cooled after running 10 minutes or so. Have had similar issues with coils that are weak and need replaced.

 

You've got to take the fuel line off the tank and run with an auxilary tank. With your new fuel lines that will tell you whether it is fuel system issue or the tank now. You should be able to take the cowling off and view the internal fuel filter to see if bubbles appear during running or if becomes air only. That is another fuel system test you need to do. If those tests prove not a fuel issue, then could be ignition or electrical.

BTW the fellow mentioned earlier in Port Clinton, Mark Smith, he is the best Johnson/ Evinrude mechanic around. He is still in business but semi retired. I just had my 2004 115 Johnson tuned up and it runs like new. Rebuilt the carbs and needed new ignition coil. Was running on 3 cylinders most of the time for last season and a few months. Runs like a champ now. Reminds me I have to call him and thank Mark. His number is (419) 734-2224. Let him know I recommended him please. Others on this site recommended him to me 18 years ago when I got my first Johnson boat. Never a bad experience. He will tell you everything you ever want to know about your motor.

Let us know how it goes,
Rick Pichola

 

Thank you all. Dad has his motor at a shop in Indiana. Hope they can get it back to him ASAP.

 

Let us know what the problem was.

 

Update...

Dad has his Etech/boat at a dealership in Hamilton Indiana (bout 90 miles from him). They tested and tested and tested and came to the solution that they believe it is a fuel pump issue. New part ordered, we shall see if that fixes the problem.

Funny story...the tech must not have believed Dad when he told him it would stall out after 15-20 minutes. Poor guy got stuck out in the middle of the lake....
