I edited my post earlier but didn't hit save.

Yes, I'm not sure everyone carries the XD-100 at this time..
However, many people don't have the E-Tec set to use XD-100 as you can set it for either XD-50 or XD-100.
XD-50 seems to be available everywhere you can buy 2 stroke oil.
I haven't checked all the places for XD-100 availability.

I don't have an E-Tec
I still have my 1985 Evinrude 150 and use the XD-50
Can't take my boat to Lake Tahoe which I would love to do.
Have to buy a new clean engine to do that though.

I guess it also depends on whether or not he has a good Yamaha or Evinrude dealer near him. A good dealer can be important if he would rather the dealer work on the engine when needed rather than doing the work himself.
The Evinrude needs no service for 3 years or a break-in period.

I'm not pushing either engine other than the fact I still believe in clean engines.
I would have suggested the new Yamaha 70 4 stroke or the E-Tec 90 for clean engines. Now with those two choices, the E-Tec is proven itself for 7 years where the new 70 4 stroke is well.... New and not proven yet....
But he didn't ask about the newer 70 Yamaha 4 stroke even though he is moving up from a 60 hp motor.

As far as working on the new engine ourselves.
How many new engines need work done to them? I don't think I would personally buy a new engine because I could work on it. It should be under warranty for many years and run many years beyond that without me having to work on it.

My old Evinrude seems to keep on going without me having to do much to it.
I guess I'll have to wait till it really breaks down before I decide to work on it myself, have someone work on it, or just buy a new engine.
