Do not forget that your operators guide states that you have to use XD-100 in freezing weather for proper lubrication.
When operating in conditions under 32°F
(0°C), Evinrude XD100 oil must be used.
The following 2–stroke outboard oils are recommended
for use in your Evinrude E-TEC
• Evinrude XD100 Direct Injection Oil
• Evinrude XD50 2–Stroke Oil
• or a synthetic TC-W3 NMMA-certified oil
Evinrude XD100 oil is preferred for your
Evinrude E-TEC G2 outboard. This synthetic
formula oil provides uncompromised lubrication
and superior performance, even in
extreme conditions especially in cold temperatures
down to 0°F (-17°C).

If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
Just cannot see why one would choose to use 50/50 vs 100% synthetic.
