FICHT's have 2 oil lines going between the tank and the engine. There's a feed and a return line. Going to have to check them, but if they're original, replace them. You should replace them about every 5 years or so just like fuel lines. As to it smoking, a FICHT engine should be clean pretty much all the time if you're running good oil in it. You are running a DFI oil in it, aren't you? If not, that is a sure fire way to kill one of them engines. Regular TCW3 oil is not up to the task of oiling a DFI engine, and you should really stick with a DFI oil like XD50 or MERCURY's DFI oil for it.

It has had the Evinrude TC-W3 synthetic most of its life. I will definitely try the other.

Listen to thefermanator he really knows his stuff

Just ordered some online :)

Also ETECs can be set up to run at 50:1 or 100:1. Don't know about the fichts, but I would want to know what it's set at and run the best possible oil.

FICHT's are strictly 50:1 as brp xd50 and xd100 wasnt around for the FICHT's. OMC thought regular tcw3 was fine, and it was one of the causes of so many FICHT issues. The 150/175 had most of its cylinder failures from carbon buildup from tcw3 oil.

Will hopefully get to run it tomorrow with the XD50. Also the injectors and lines were good. Mechanic determined it was overfilled at some time in the past. The oil had been there/transom a while. Thanks for the help

So far so good. Ran it for a few hours. It still smokes with the xd50, so I will just leave well enough alone.

With that engines reputation, don't take any chances. I would say have it checked out just to be safe. Also run some ring free in your fuel as carbon buildup will destroy that engine.

Last outing
 

Smoke was much better last trip. Added some oil last trip and did not overfill. Oil is back. About to get the the hatches worked on, re-gel coated, maybe stain the teak, and will try to get it to a top notch evinrude guy a couple of hours away during the winter. Want to stretch the motor out another year or two for sure. It has run great overall.
