See full version: What is the oil ratio for a 2 stroke Evinrude
Likewise, what is oil mixture for 2 stroke outboard? 2-STROKE OUTBOARDS (CARBURETED) Normally your Tohatsu outboard uses a 50:1 oil/fuel mixture (500 mL of oil for every 25 liter of gas). During the break-in period you should use a 25:1 oil/fuel mixture (1000 mL of oil for every 25 liter of gas).
Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel. But running a two-cycle engine with too little oil can actually destroy the unit. more
Valvoline 2 Stroke Outboard Oil is suitable for use in Evinrude, Mercury, Mariner, Suzuki, Volvo and Yamaha engines requiring 25:1, 50:1, 100:1, petrol/oil ratio, including those outboards with oil injection. more
Can Running Rich Damage The Engine? Running rich will very rarely damage an engine. However, running too rich for too long can cause problems long-term that will affect performance and reliability. Rich jetting will foul a spark plug more easily. [links]
Evinrude outboard motors made since 1964 require a 50 to 1 fuel to oil mixture using 6 gallons of gas per 1 pint of oil. Motors made prior to 1964 take a 24 to 1 mixture. more

With too much oil in your engine, its fluid level in the oil pan will be so high that it can be splashed by some of the moving parts in the engine block, specifically the crankshaft lobes and connecting rod “big ends.” That, in turn, can whip the oil into a frothy consistency, like a well-emulsified salad dressing.

Any advice would be much appreciated.
Brute, It is easy to verify the OMS pump is working properly. Simply fill the oil tank to the top. Now run a tank or two of premix fuel. Now refill the Oil tank to the top and note how much oil it takes. My '98 Johnny 150V6 runs at about 60::1, so you would see about 13oz oil used/six gallons of fuel. here
I have a 1996 Evinrude 150 V6 intruder. I purchased the motor used and was told by the previous owner that the motor wasn?t drawing 2-stroke from the reservoir and that I must pre-mix at 1:50 ratio (which I've been doing) and keep enough oil in the reservoir to prevent the reservoir low oil alarm from going off. I have only been out a handful of times and used less than 3 tanks of fuel. The motor runs like a dream ? no hesitation on take-off and smooth through all rev ranges. On my last trip the low oil alarm went off indicating that the motor is drawing 2-stroke from the reservoir. I have a few questions.
if the fuel side on your Pump is still working it is very simple. unplug the 2 line harness going to the oil tank, unplug the 3 or 4 wire harness, going to the Vro pump. cut and cap the oil line going into the motor. add oil to fuel tank, mix well, then remove fuel line at top carb, catching gas in a container, pump the fuel line bulb until you get premixed gas to the carb. you can tell as it will change color. put line back on carb, and go boating. more
Outboard boat motors with two cycles manufactured by Johnson and Evinrude after 1964 require a 2 percent fuel to oil mixture. Use 1 cup of outboard motor oil for every 3 gallons of gasoline.
The oil needs to be manually added to the gas tank unless the engine has an automatic oiling system. If the motor was manufactured before 1964, a whole pint of oil should be added to three gallons of gasoline. The addition of oil to the gasoline causes the gasoline to become thick and clog the fuel lines. Only mix the amount of fuel needed for the day. If there is some left in the tank, do not let it sit for long without cleaning the system. here
