What is correct '97 Ficht motor oil?

[Barnacle Bob]

What is the correct outboard motor oil to use?

1997 Evinrude 175 HP FICHT Ocean Pro (oil injected)

The man that sold the used motor said Evinrude XD-50. Is that correct?

If XD-50 is not available should I use XD-30 or XD-100? These are all Evinrude labeled oils.

(Remember me? I am in Guatemala and you helped me diagnose an ignition module problem. A new module got the motor running fine but now Guatemala seems to be out of XD-50. Help, what oil do I use)?

I don't know about XD-100.
You can run XD-30.
I run XD-50.
XD-50 has a higher viscosity so it is generally better for running at WOT and pulling skier and tuber.
XD-30 is thinner and will work, but may start to break down if you're running for extended periods of time at higher RPM's. I have used it in my engine before and nothing went wrong. XD-50 offers me better protection for what I do.
