250 Ficht Shuts Down

[gpetrilak]

Have 2 - 2003 250 Fichts on a 34' planing hull, 700 hours on them. Complete service 30 hours ago including plugs and filters.

Engine shuts down with no alarm lights or horn after running for 1/2 hour around 2500 - 3000 rpm. When trying to restart, alarm lights sequenced, turned off and then 3 lights lit up, No Oil, Water Temp and Check Engine light. Engine would not crank, didn't hear start relay click.

Waited a few minutes and tried to start it, the 3 alarm lights took a second to come on, another few minutes 2 seconds to come on etc. After 10 minutes, no alarms and it started.

Ran fine trolling at 1600 - 1800 rpm and coming back at 4000 - 5000 after this happened.

This also happened to both engines at the same time when the boat was re-launched a month ago after doing some WOT runs ( 5500) with the dealers tech aboard. His Palm didn't find any error codes.

After the third time this happened,I suspected EMM overheating and checked the water cooling thru the EMM. Pulled the hose going into the vapor separator and found very good water thru the EMM. Blew thru the separator, no obstruction.

Has anyone seen this behavior before ar have any ideas ?

Re: 250 Ficht Shuts Down

i agree with you it sound like somthing is over heating, but what? and why on both engines. i would do some checking on elements that are common to both engines.

Re: 250 Ficht Shuts Down

It only happened on both engines once. Since then, only the starboard engine.

The engines have separete fuel and electrical systems including separete batteries.

This could have been written by me....

I have had this problem with my port enginen since Aug..

Taking to mechanic today for the 4th time... contacted evinrude and they will guide the tec Mech...

If you find out anything please leave note or e-mail me....

I will send you info on what I find out.

My dealer thinks it is the EMM but is contacting a BRP engineer he knows. We may try swapping out the EMM with a used one he has.

My solution is to take off the mounting nuts and hope they both fall off, then put on some Yami's.

Hello Had same problem and emm was blammed . I found a weak connection on the blade fuse that is hidden on top of engine starboard side along wire harness. when emm fails it should show a stored overheat code in computer.

Re: 250 Ficht Shuts Down


One problem that could cause the motor to quit after running a while and not storing any error codes is an injector that is drawing more current than it should (but not enough to blow the fuse) and that makes the internal EMM electronic components get hotter than normal. The EMM eventually shuts down then fires back up after it cools.

Re: 250 Ficht Shuts Down

I will check that fuse connection. We will be changing the EMM tomorrow and will check for any error codes.

Seahorse5, even though I found good water flow thru the EMM I think you are right about the overheating. After the last shutdown I immediately pulled the cover and found the EMM case temp seemed to be just as hot as the flywheel. I felt that he EMM should have been cooler. Can the injector current be checked with the diagnostic software ? Or maybe compare the injectors coil resistance to see if one is lower. The Clymer manual I have doesn't have any coil specs.

gpetrilak, The BRP Rep was at the shop today!!!! After checking an few items he feels that the problem is with the EMM. The new EMM should be in Monday. If the seas are OK down here I am Hopping to try it the following Saturday or Sunday. Will post the results. Let me know how you make out.

First of all you need the FACTORY service manual, no ifs ands or buts !!!!!

An EMM is normall hot to the touch due to its own heat but also from the hot motor and the air around it.

When I say it gots hot internally, I mean an individual electronic component is heating up due to high current and possibly causing an open circuit in it or in a connection. That's the kind of problem that is very hard to find and does not produce any error codes.

To test the injectors, check the resistance on each, then use a digital ammeter and a mini-fuse adapter to monitor the amperage draw of each pair of injectors. After you do that for the 3 pairs (6 injectors) you will see if one pair has a higher draw than the others. Then you narrow it down to which one. It is time consuming, but that is the only way to check them out. It is very very rare though, but it does happen.

Re: 250 Ficht Shuts Down

We changed the EMM and a 1/2 hour test run went ok. Won't know for sure until I do a 4 or 5 hour run. Seas are running 10' right now so I will wait a while. I will do a resistance and current check just to eliminate another possible cause.

I know I should have the factory manual but I am just trying to keep this rig running until my new 38' boat with diesels is done.

Re: 250 Ficht Shuts Down

Did a 4 hour run and everything looking good so far. Will still check the injectors when I get 'around toit'

dI was able to take the Boat out last Weekend and it performed great!!!! It was the EMM... Well after lots of money and time, finally they fix the darn thing.

How much time was spent finding the problem? Did you have it to different dealers? Did the dealer(s) take the boat out and duplicate the engine stoppage, or was it an educated guess?

Glad to hear that you have the problem corrected, intermittent malfunctions are the worst to find, and usually the most expensive.
