What does oil injected outboard mean?

The Optimax is a direct fuel injection motor. Gasoline is sprayed directly into the combustion chamber. If the oil injection system is removed and oil is added to the gasoline then oil is only going to be introduced into the engine within the combustion chamber.

What is an oil injected 2 stroke outboard?

2-stroke outboards generally have an external oil tank with the oil and fuel mixture injected into the cylinder. The oil is consumed and the oil tank level must be maintained, replacing oil as it is used up.

How can I tell if my outboard is oil injected?

The only way to check the OMC system is to mark the level on the tank and see if it moves. Also if it is smoking, its oiling. If you ever disassembled a VRO pump and seen how it works, you would be able to see that the pump can’t pump fuel without pumping oil also.

Which is the Best Outboard oil for direct fuel injection?

If you are looking for a product that cares for your direct fuel injection (DFI) engine, look no further. The Mercury 2-Stroke outboard oil provides increased lubricity, reduces smoke, carbon deposits, and protects the motor. Your engine will improve performance, and will fall in love with it. It will reduce pollution and optimize consumption.

Why is my Oil Injector not working on my outboard motor?

Now and then with certain models of outboard motors, the oil injection system will appear to not work properly. However with most oil injection systems, this is a wrong diagnosis. It would seem that an outboard motor can damage itself by running lean, but in actuality, an engine wearing down due to running lean is not related to oil injection.

When to disconnect oil injection from outboard?

Run your outboard until you see a noticeable increase in the amount of smoke coming from the exhaust and/or the outboard runs rougher than usual at idle. The idea here is to BE SURE your pre-mixed fuel is running through your Outboard BEFORE you disconnect the oil injection system!

What happens to oil in an outboard engine?

During extended trolling an outboard may not reach normal operating temperature and even with modern fuel injection and engine controls, unburned fuel in the combustion chamber can condense and migrate past piston rings and contaminate engine oil, a situation engineers call “fuel dilution.”
