Etec! Hesitation!

[RDOCK]

2007 150 HP Etec. Model 150DHLSUF. Serial G-05175457. I have that hestation when going from low speed to high and loading it on trailer! My mechanic said he called BRP and they told him this is normal! Everything else checks out fine. I found an article on BBC from 2008 about drilling a 1 1/2" air metering hole In the air silencer. Has anyone done this and does it help! I would think BRP would let mechanics know if this was a fix! This hesitation really bugs me! Once I hit 2000 RPM it runs fine and smooths out! In the article I found Seahorse said it was o.k. to drill this hole!

That's the article I found! That doesn't answer my question! Does it work ,and can it cause any problems if it doesn't?

BRP did notify the mechanics 3 years ago by sending them the service bulletin that you read about on the etecownersgroup.com . Every authorized dealer should have it or can download it from their dealer support website called DealerPort.

Yes, the hole in the air box does help that particular model E-TEC

What more are you looking for?

[RDOCK]

Thank You! I will take a look and see if I can attempt this. Doesn't look to be to difficult. Can you just cut the hole or does the silencer have to be removed?

[ChampioNman]

Yes the airbox must be removed for this procedure.

[RDOCK]

Again! Thank You!

My friend has a 2007 Etec 225hp and his is doing the same thing....Is this procedure for any Etec size motors?

[SEAHORSE]

no

[RDOCK]

I did the procedure and it was fairly easy to do! The bad news is I still have the hesitation! No change! The only change will be this is my last ETEC! It doesn't seem as though Evinrude is attempting a fix for this and it seems there are a lot of engines doing it! Make sure you try your engine before you buy! They won't help once you drive off the lot!! They just tell you this is normal!!

Sounds like you have a problem with your dealer, not Evinrude. If your dealer did not even attempt the factory service bulletin, then he or she is not doing what they should.

They all don't have a hesitation problem when set up correctly. What boat and prop size do you have and what is the top rpm with full fuel and a few people aboard? What is the throttle position sensor calibration at? (ask your dealer to give you the engine printout report?

Have you called Evinrude customer service and told them that your dealer has not fixed the problem?

[RDOCK]

My mechanic told me that he called and the Evinrude tec was the one that told him this was normal because it's where the engine switches from low speed to high. I was running a 24 Raker and was only hitting 5330 rpm. I am now running a 22 Raker and have hit 5681 with a light load and full tank! According to an 0ptimim Rpm. chart I found it calls for 5300-to5500 Rpm. I have the print out report on my engine. I don't see where it says anything about throttle position sensor calibration! What would it be under? I only see something that says TPS out of idle range! I don't want to sound nasty but when a mechanic tells you something what else are you suppose to do. You can only hope he's telling you the right information. Also at $96 an hour it's hard to keep going back and we only have one certified Evinrude mechanic in our area. The dealer I bought from went out a year after I bought. I guess I will have to take this up with Evinrude. Do you have the best phone # or the name of someone I can speak with? Thank You!! Whoops after a second look I see TPS Cal on the report and it says (199 ) The 150 is on a 18'6 Stratos 285 XL.

Definitely talk to customer service, have the serial number handy - 262-884-5993

There is a point where the combustion transition occurs, but there should not be a hesitation. That 5300 rpm prop probably contributed quite a bit to the hesitation going onto the trailer. The 5600 rpm prop should make the motor run the way its supposed to. Also the exhaust sensor tube should be taken out and cleaned if needed. Most places either do not know about it or neglect it. There was also a mid-year change in the throttle cam on that motor. It's hard to tell them apart but they are not real expensive to replace just to be sure.

199 for TPS is in the ballpark , but it should be double checked as many times around 185 or so works well. Talk to your tech, he should be able to show you an E-TEC service school diploma within the last few years.

Thankyou! I wish I lived in Alabama my boat would be out in front of your house. I will call Evinrude but it sounds like you covered most already. Part of the problem is the mechanics in our area are not on the water and they don't take the time to put it in and try it!

Most times you don't have to be on the H20. The properwheel tank fixes most problems

Seahorse-- I have the same engine and the same problem. I was told by an Evinrude certified mechanic (and this guy is good he has replaced # 2 piston on my engine after another dealership replaced the powerhead for a problem with #2 cylinder)that he has discussed this issue will BRP tec support on several occasions.
And they are telling him "I will have to live with it" something to do with the changing from low speed jets to high speed jets. I know when I power load my boat it is hesitating before it hits 2000 rpms, and then it jumps on the trailer. NOT
GOOD. I would gladly take my boat to BRP if they can fix this problem. I have been an Evinrude man for 40 years, but this issue has me wondering. And I have the 1 1/2 inch hole in my air box. as the other owner has said this is not an isolated problem. I respect your knowledge, maybe you can help us out. Thanks for you attention. (And my motor runs great when you get it above 2000 rpms or below 1000 rpms) and i am running a 23p Tempest Plus at 5600 rpms&lt;br /&gt;&lt;br /&gt;

If you have a hesitation problem, insist that your tech call his toll-free dealer tech-help line and talk to the folks there. They are the dealer problem solvers when a sticky situation crops up. They are not babysitters for the dealer, though.

There may be different MAPs or adjustments that can be done on a case by case basis.

[ezellmer]

In 2007 our ski team was having issues with throttle jump at low rpms and a change of MAP together with trial and error on the TPS setting cured it. Engine operating temperature also seems to have alot to do with it.

I was out today! Water temp 48! Now I'm getting slight surges at around 4000rpm. Called E-Rude and all I got was "could be this" could be that! Oh and as usual PLUGS! Do these marine engines really eat that many plugs. It's hard to believe a car or truck can go 100,000 on a set!

[stratos285sc]

Just a QUESTION-- Does Evinrude ever send a tech out to meet with a customer
and ride in his or her boat to see what the engine is realy doing. I wonder what they (Evinrude management) would do if they were pulling their vehicle into the garage and it surged and they ran thru the garage wall. Would they think there was a problem with the vehicle????? Maybe bad plugs. Do I sound ticked? YOU BET. When you hit your against a wall you find out that it hurts and then you stop. After 5 years you finally give up. I was out yesterday too, and the same old crap. You would think that Evinrude would address this issue without being called constantly by P-off customers. I wonder if they have ever heard of a recall?
I know Evinrude is getting publicity in our area, but it isn't the kind I would want.
I work at one of the big box stores and if our customer service was like this there would be some top level managers looking for work. Guess I have vented enough.
And by the way, yes I have called tech. service (several times)
