Evinrude 75 Ficht

[Nickytynick]

Hi all.

I wondered whether anyone may be able to shed any light on an engine problem I am having.

I have been helping a mate with a boat project and in doing so have fitted a 2001 Evinrude 75 Ficht.

We saw the engine running on the previous owners boat with no problems. It has only done around 120 hours and seems like a sweet little engine.

Only problem is that having had it removed form the previous owners boat by a marine engineer we have now fitted it to my friends boat and now have a warning light.

The warning light in question is the CHK ENG (check engine) light which dispays on the rev counter.

Having connected the battery for the first time, we turned on the ignition and the ECU did the self test where all lights extinguish one by one. But then the CHK ENG illuminates permanently.

We have checked the oil and fuel lines and primed and bled both, also checked all the plugs which were disconnected by the marine engineer.
All seems OK.

Tried starting it in the water and it runs fine on tickover and in gear with a few revs but the buzzer sounds for ten seconds and the light stays illuminated. We have only run it for 10 - 15 seconds at a time to see if the problem will just 'go away' to no avail.

Any ideas on what else we could check would be much appreciated.

go on to boat setup . com , and they have a few evinrude experts on there . by disconnecting the throttle censer , you can 'blink' the fault codes out of the engine , and find out what the faults are. But i forget what the sequences. boat set up will have it.

IF the light stays on right after the self-test, then it is possible that the gauge is bad or there is a direct short somewhere along the tan/orange wire or a stuck vacuum switch on the engine. It measures the vaccuum in the fuel system. When it gets beyond a certain threshold, like a restriction , the alarm goes off for 20 seconds, and the light comes on.

Otherwise the check engine light can mean you have a fuel restriction of some sort

You probably need the diagnostic software and the lead. There is usually someone selling the kit on Ebay. Some versions only run properly under either a very old version of windows or, better still, dos.

Once hooked up, you can interrogate the ECU and see what is going on.

Failing that, go to Fairweather Marine in Fareham. They know these engines.

Thanks for all your advice guys.

Took it to the engineer who diagnosed an air temp sensor out of range.

Replaced it for £90 - all OK now.
