I just downloaded the Rotax Operators Manual. This manual includes the 582 mod 99 engine which is what I have.

On page 11-2, section 11.1.3 is found the procedure for storing the engine for periods longer than 4 weeks up to 1 year.

The first 4 steps are:
- proceed with preservation prior to engine stop and on the engine at operating temperature
- let the engine run at increased idle speed
- remove air filters and inject approx. 6 cm[exponent 3] of preservation oil or equivalent oil into the air intake of each carburetor
- stop engine

So tell me - is anyone really doing this? Who in their right mind would stand 12" from a turning propeller to do this? I kept thinking that I was missing something but the steps above are pretty clear. So clear, in fact, that I still think I must be missing something.

I just bought a Quicksilver Sport 2S and I will be storing it soon. I have other questions about the right oil to use for this procedure, how to "inject" it, etc. But I have to understand the first four steps first.

I know at least one person here must have stored their plane for the winter...

I will also send an email to Rotax but thought I would get some help here too. Thanks in advance!

    Mike,

    You've got the procedure right. Its not as dangerous as it sounds. The preservation oil can be bought at most marinas or boat dealers. It comes in spray cans. Just remove the filters and spray it in the carbs with the warmed engine running at idle. By the book, I would agree that it is the best way to store the engine. In real life however, I don't know many people that do it. If you are going to store the plane for several months without starting it, I would do it. I personally prefer to start the engine about once a week and warm it up for a few minutes. This not only lubricates everything, it also freshens the fuel in the carb bowls and fuel lines and relubes the gearbox gears. I also plug the exhaust pipe and wrap the filters in aluminum foil to keep out moisture.

    Bill, the thing that I don't understand is who, in their right mind, would attempt to stand anywhere near a turning prop on a Quicksilver, with all it's wires and tubes, and remove air filters and spray inside?

    You'd have to be standing within 12" of the prop! Wouldn't it be better to stop the engine, remove the air filters and spray the lubricant, put the filters back on...THEN start the engine and let it run for 2 minutes?

    I've seen discussion that one should run the engine to full operating temperature to be sure that any water vapor is emitted rather than let it run long enough to make moisture but not dispel it. Perhaps I'm reading your post wrong and you do, indeed, run it up to full temperature. Some have said you ought to run it for an hour but that is probably just one prescription and not necessarily founded in science.

    Mike,

    There is one other way without getting near the engine. Its a little more complicated. If you have a primer on the aircraft, you can spray the preservation oil in a cup, disconnect the primer line from the tank or gascolator, put the primer line in the cup and pump the oil into the running engine with the primer pump. Since the primer bypasses the carb bowl and jets, the oil will go directly into the carb throat. Don't run the engine more than a few seconds after you apply the oil or you will wash it all out.

    I do have a primer instead of a choke. So maybe that is possible. I have not heard back from Rotax yet. The procedure might be easier to do with the wings off so you can get to the air filters easier. But you still would be way to close to the prop.

    What oil would you use and where can you get it in a spray can?
