I have gotten 96 ELPTO with oil injection, have not had time this winter to take it out yet.
Just have few concerns in regards to reliability of oil injection.
1 What kind of maintenance does it require?
2 What to look for to make sure it is functioning properly?
3 Is there any alarms that will alert of malfunction?
4 What years of the motors that had reliability problems? is 96 OK or should I disable it.
5 Does anyone mix a little oil in the gas just in case?
Just interested in your experience

Dini, You need to check the function of the sensors to assure they warn you of a malfunction. That system has two resvoirs. The large one in the boat is pressurized by the motor via a check valve and crankcase pressure. This pressure forces oil into the motor-mounted resvoir. The motor-mounted resvoir feeds oil via gravity to the oil pump which is powered by the crankshaft and controlled via linkage to the throttle. As long as the sensors are working, you can tell if the system fails. They are reliable, and have been around a long time.

BTW- I do not think mixing oil into the gas and running the oil injection is feasible. If you mix enough oil to protect the motor should the injection fail, you might as well mix a bit more, and disconnect the injection. After all 50::1 mix is 2.5oz oil/gallon gasoline. You would need to add a minimum of 1.28 oz oil / gallon gas for any fallback protection(100::1 at idle is likely Ok), so you may as well premix and forget the injection, IMHO.

1. Keep the oil clean. Some recommend you pull the pump and inspect each spring startup maintenance.

2. Oil in boat tank, Engine tank plumb full tight, Power On Self Test beep sequence when you turn the key on.

3. Low oil or lack of pump motion when engine is turning.

5. I mix about an ounce of oil per gallon in the main tank. I use full synthetic oil, so I think it would probably keep it in one piece if it alarmed until you stopped the engine. A spare quart kept onboard would then be mixed with the main tank to get back to the landing. The slightly richer mixture doesn't seem to hurt. PenZoil full synthetic burns very clean anyway.

Like anything mechanical, they can fail. I think the VRO system is probably more reliable than I am, and certainly more reliable than my teen-ager.

hope it helps
