Re: e-tec 25 hp loses power at high rpm

So has anyone figured out any more about this issue?

I did the nylon string thing and it did work...thanks.

Bought a new Eninrude gas line but problem came back.

Tied them up again.

Heading in for a new tank tomorrow.

Frustrating problem...dropped out of plane and high revs 4 or 5 times today.

Is there something about the Envinrude connections?

Seem good for awhile then get loose?

Re: e-tec 25 hp loses power at high rpm

It is hard to see what your connections are doing. A trained tech with clear hose, a vacuum gauge and a pressure gauge can determine if you have a fuel delivery problem at high speeds.  Evinrude does have a factory support team of technicians who assist dealers with hard to diagnose problems. Talk to your dealer about taking advantage of that service if needed. This is for dealers in the US and Canada.

Re: e-tec 25 hp loses power at high rpm

My 30 etec has left me straded 5 times in the river. Mechanic finally figured it out by calling the evinrude people. There is a service bullitien out for this part. . The new part must have a "c'' on it. What happens is that the bolt holding this part on gets hot from the engine heat. I t expands and makes the hole tighter than normal. This makes the throttle stick and go into safe mode. The new part the hole is a lottle bigger. Problem solved. Part number 5005187.

Thanks for the tip. 

Will get the engine serviced this spring and have the part replaced.

Hopefully it puts an end to a pesky problem.

Otherwise engine runs great.

Re: e-tec 25 hp loses power at high rpm

What part are you talking about, I am having the same problem.

is it a part near the fuel line connection, to keep the connection tight so it doesn’t suck air ??

thanks.

Re: e-tec 25 hp loses power at high rpm

I have a 2012 30 hp e-tec and I took it out on the water yesterday and I cant get to full throttle. The last trip out I ran the oil real low so it went to limp mode and got me back to the dock. The lights never came on or anything while I just over idled back.

So back to yesterday. I had the oil topped off and went out to run the boat and I couldn't get on plane. Just basically idled to where I went and came back.

 

Is there a reset do I have a bad plug it basically just stutters when I go to give it alot of throttle. Any help would be great just had it in for service a month ago and don't want to go right back for an easy fix.

You could have something as simple as the throttle being slightly open when you started the motor or a sticky shift switch on the motor. In either case the motor will not rev up high or develop power if either condition exists. 

There may be other factors such as plugs, linkage, etc. that could give similar symptoms. See your dealer as there may be a software update also for your motor plus the tech can check out the obvious items and run an engine report.

Re: e-tec 25 hp loses power at high rpm

I had a similar problem with engine going to idle while I was on the plane. I found my oil reservoir sucked in so I loosened off my oil cap and haven’t had a problem since. I read the oil cap has a vent in them but they can clog up. Worth trying

Re: e-tec 25 hp loses power at high rpm

I recently Purchased a used 2019 etec 30hp on first run the motor revs up and runs fine for couple of minuets then drops to idle pull the motor to Neutral and it Immediately runs fine agin for couple of minutes then the same thing. Doesn’t do it intill you Hit 3800 rpm and above runs fine below 3800rpm. Motor is on a bigger boat and will not plan out at full Throttle. motor is running at 4700 rpm at full throttle. wanted to ask about this problem before installing a smaller prop.

Re: e-tec 25 hp loses power at high rpm

As an Evinrude dealer tech I would first check for any stored codes that may be putting your engine into S.A.F.E. mode and limiting your rpm to 1200. Then fuel supply system tests and possibly inspecting the exhaust system for damage. You maximum rpm is at least 800 rpm too low so just a lower pitch prop may not get your rpm up to where it need to be for proper engine loading.
