Any Outboard Motor Expoerts out there?

[paraflyer]

Just had a minor brainstorm....but I need to know one thing: Does this engine have full electronic fuel injection?

If so, could be a leaky injector module; easy way to tell is to note the following: is there a big belch of smoke when it's first fired up (as if it's choked or running too rich)?

The "smoke on startup" would be caused by pressurized fuel in the line from fuel pump to injector module leaking after engine shutdown, the fuel would be essentially laying right at the tips of the poppet nozzels (point at which the fuel is injected into each cylinder). Ends up being too much fuel present right at startup.

BUMP.

Any results yet?

How about a bad coil . I had a Truck that would do the same thing run great until you started to push it... Then it would die... If the fuel system is not your problem then it has to be timing or spark... P.S Did you check the Batt ??? Try a different Batt...

Battery is Brand New. All the timing and spark, coil, ect.. have been checked by the dealer and seems to be ok.

Im not sure about the injector. To my knowledge, the motor is not smoking on start up. I will forward that question to my father. But I do believe that everything is electronically controlled. The computer was checked and reprogrammed by the dealer as well.

Quick reply from dad:

"No Smoke and batteries and coil have been checked.

I have cleaned plugs replaced both fuel and water separators. Will test this weekend."

How is the flow of of cooling water ??? Maybe something got sucked into the cooling system blocking it at full throtle ??

[Diver01]

It should be ok, I believe that was checked as well. Ill ask him about it though

UPDATE:

All fuel filters and water seperators ect.. have been replaced. The Bulb is brand new. We also ran teh motor on a second temporary tank to eliminate the fuel in the boat and any vacuums being created or leaks. The motor is sill stalling out. The dealership says they can find nothing wrong with the motor. They checked the computer, coil, battery, ect, they say everything is fine.

One thing to note is the plugs are brand new but look fouled already. Im wondering if it could be running to rich? Wouldnt the dealer have found that though when he checked the computer? Any more ideas would be most welcome....

*Bangs head on keyboard*

At this point I hope to get ahold of a technician at Evinrude. This motor is almost brand new and should not be doing this at all...

Motors aren't that complicated. A shop with proper test equipment and a decent mechanic should have no problem getting it working for you. Take it to a different dealer.

Just out of curiousity, this dealer that says everything checks out fine, have they tried running the motor at full throttle? Does the motor EVER run proper at full throttle or is this an intermittent thing?

The motor ran great at full throttle when the plugs were Brand New. It lasted about 2 short trips.. not even an hour each time out. Now the brand new plugs looked fouled again (BLACK) and it will not go over 3000 rpm and it eventually dies. (I believe the computer is killing the motor somehow cause when you shut it off and turn it back on again, you can go back up to 3000 rpm.. rinse and repeat... )

So it does run well for a short period of time? Hmmmmm...that's a little strange. I'd let another dealer have a look at it. Whatever the cause, chances are that if they didn't find it the first or second time they won't figure it out on the third time either.

If you put brand new plugs in would it last another 2 short trips or would it run like crap still? Maybe somehow water is getting where it's not supposed to when he takes it out.

Well, to see if it's the plugs, fire it up and run it till it bogs down.

Shut down, then immediately put it a set of new plugs (yes, I mean when the engine's still hot, so be careful), fireit up again and take it to speed.

If it doesn't bog down right away, then it's not the plugs. I'm still inclined to think it's fuel-related.

You said the "plugs were black".....dry carbon, or wet and oily?

[Diver01]

The plugs are black and dry ( SOOT).

We actually tried your idea already. The plugs that are in there now are brand new. They have less than 5 hours on them. The engine actually ran great for the first hour but as the plugs became more fouled you can tell the engine was starting to struggle

Since the entire system was run on a buddy tank, it seems unlikely that the fuel is the problem. All teh filters and water seperators and the bulb are brand new as well.

The main problem with this motor I believe is the overall design. OMC went out of business because of the handling of the Ram FICHT technology. Bombardier bought OMC in court and fixed the motor. One of the things they did to fix the motor is design a new electronics system to combat plug fouling at low RPM ranges. (Basically the motor is not running hot enough) What I need to find out from Bombardier today is if the electronics in this motor can be upgraded to the 2002 model year. I will be calling there service department at lunch..

Ill keep you all up to date.

thanks for the ideas
