etec issue

[sailboatmike]

I have no problems with the ETEC, I love the idea that someone decided to make a less agricultural and more fuel efficient motor for a boat. I even went up to the local Evinrude dealer to get a quote, but he was out and never bothered getting back to me, and the ebay thing scared me as I said.

We have been ripped off for so long paying huge $$ for low tech motors that if they were on anything other than a boat would just be a laughing stock, and then jut to add injury to insult or run salt into the would some more they huge huge prices for simple replacement parts.

I needed a couple of bolts for my Mercury, I went to the local Merc dealer (he is a nice bloke and I think apologetic for the spare parts prices) 4 x bolts was going to cost me $32 (genuine Merc spare) but he had run out of them, so off I went to the industrial bolt supplier, same bolts, same material $4.00 for the 4.

I think if I was repower again I might choose a Parsun at just $6500 for the 75Hp 2 stroke its around 1/2 the price of the big names and they seem a reasonable motor from the reviews

Sinice this occurred after running the engine dry, I would suspect air in the fuel lines. You may want to put it in fast idle mode to purge any air out.

I have about two hours of run time on the motor since this happened and it runs fine as long as you do not go over 3k and it revs up to 5k and planes off but then that's when the problems come back .i saw where you can ship the injectors in and they will service and clean them for 44.00 a piece ? Is it true that new injectors have to be programmed ? I have seen this on 2 separate websites that sold the injectors but why ? Injectors fire when ecm tells them to ?

Yes, that's true. Even the sparkplugs need to be marked and replaced "just so" (the injectors inject at one precise location only) , so that the commonner won't be able to perform even this basic operation. I wouldn't mess with them. If cleaning the injectors won't fithe problem, you'll have one more thing to worry about, if the enginestarts at all

It seems pretty unlikely that the injectors are fouled up and need cleaning though, even if they have sucked up some gunk from the bottom of your tank. That's what the filters are for. Has the boat ever kept steadily at 5,000 RPM in the past?

Running dry is bad for injected engines, worse for some than others, so it is to be avoided. But since it has already happened, and you have checked filters, you might check the strainer in the tank for guck if you haven't already.

You might also check the manual to see what it recommends because running dry can damage the fuel pump.

I wondering about the v.s.t screen ? But tanks are clean and I even pulled pick up tubes out and cleaned them and replaced lines the day before I started having trouble and I have the same issue with both tanks so I dont think it is a tank issue !

Sound like the problem i have.
Runing bad and intermitent.
i call the company brp and they make an agrement to me,
suposed to help me... it thurn to be a hull of a bill and 4oo $ more than
if i did what i told them what i was suposed to do.
almost imposible to diagnose that type of problem without the computer..
be carefull with brp i have a realy bad experience with them, never recomand them.
you can by the computer kit on ebay, easy to use if you have good mechanic knoweldge .
in my case it whas the fuel injector.
good luck

Cleaned v.s.t screen ,was filthy but made no difference ?

Just did a quick check of the online manual; I saw no warning about running out of fuel doing harm for that engine, so you should be OK for the fuel pump.

I don't know if it helps or not but I was having similar issues with a brand new etec 90 last week. The symptoms my motor was having were similar to yours. I could idle for days but as soon as I put a load to the motor it was like it was on a timer. About a minute or two, or a half mile from the dock she would shut down like clockwork every time. I have the Icon gauge and was getting no fault codes either. Got the dealer out on the water with me and hooked up the computer. Nothing. Well we kept digging and it turns out the fuel line was pinched at the grommet entering the cowling added to the fact that I wasn't running a fuel demand valve on my fuel line. After we addressed those two issues she has purred like a kitten. I was terrified I had run bad gas through the motor but my filters were clean. Like I said, this may or may not be your problem but it might not be a bad idea to check just for giggles. Good luck!!

Thanks for input. The filter stays full ,I believe its a injector problem ? Vst filter was pretty nasty ......

[bahama bound]

Engine runs great up to 3000 then starts skipping ,think I'm gonna replace it with a new one ,I think its a 2009 supposed to have 86 hours but I want to get another 90 anyway ........... This is a 75 etec .i honestly believe if I had changed filters it would not have gotten trash in injector but like I said they clean injectors for 44 bucks a piece .

[aviro]

Maybe your engine is runing in safe mode
due tothe fuel starvation .
it is about this symptom.

When it acts up it runs pretty rough ,I wonder about that too ,enough water pressure ? It pumps water but not as strong ? After I cleaned filters it seems to run better ,unplugged top injector when it acted up and it made no difference.so I assume its the top injector .

Make sure you are not using the new EPA gas caps with the pressure valves. They do not work with ETEC motors without modification. Break the valve out of the cap then drill a 3/8" hole in the cap so you get good ventilation for the gas tank. The ETEC at high RPM will not put enough suction on the tank to get the EPA cap valve to open up. When I leave the dock I just unscrew the gas cap vent screw and put it in my tool bag to make sure the tank is fully vented.
