Evinrude Ficht WOT Issue - Suggestions Please

[rayd]

Running twin 2000 225 Fichts. Port engine will not run above 4200 RPM at WOT. Fuel consumption at 16+ gph on that motor, while Stbd runs at 12 for equivalent RPM.

-Replaced plugs, gapped at .28, indexed
-No error codes from EMM
-Ran diagnostics on all injectors, seem to be ok
-Replaced prop to eliminate hub issues - same result

Any ideas or suggestions would be greatly appreciated. Thanks.

Did you ever do a compression check on it ?? How about prop size ??

 

[rayd]

Have not done a compression check - will definitely get to that, but won't have ability to do that for at least a week. W regard to prop size, been running these props for years.
Also, a bit more info - ran seafoam and decarb through yesterday and the motor ran perfectly for 15 min or so. Cruising at 4400 and she just dropped out, rpms fell and to get to equivalent had to almost go wot - but again no error codes or alarms. Sure did seem like a cylinder was not contributing...

Inspect all of the wire connections on the injectors for corrosion or pins not making contact.
