long story short i put 200ml of oil in the gas tank thinking it needed mixed fuel. ran the boat for 5 minutes and everything was normal.
should i drain the gas tank or should i be fine?
Evinrude V4 90
 
200ml ??? 6 oz? if you have more than 5 or 6 gal tank you will be, might foul your plugs a bit maybe. a little richer mix is always better than a little lean, my motors been ran with an ounce or so of extra oil in the tank(6 gal) for 32 years and it has not hurt nothing....
 
What year is the 90 HP V-4 -----1964 / 1965 ----------------early 1980's or later with oil injection.-----------If a 1965 with a 5 gallon / 22 litre tank then 200 ml is not enuff oil !!------Make sure you get the mixture correct or you will damage a fine piece of machinery.
 
early 90's with oil injection, stupid me didn't know about the oil injection.
only used 200ml because all i had was 10L of gas to add to the tank
 
On some motors the oil injection system has been bypassed.----It is important to know exactly what is going on!!!---------A little extra oil in the fuel has never done any damage.
