    Can some one tell me how to tell the year of Manufacture from the serial NO. on the engine. I have an engine that has never been run, plastic plugs still in place, with no identifying sales information.
    Have no idea what shelf life is!
    Thanks,
    Johnc

    You are going to find that information hard to come by.....been there and done that.
    Rotax wasn't too keen on letting their "in house" information flow to the outside world.
    The best you are probably going to do is find a general time frame of when that engine was produced..what series..basically from what year to what year for that production run....not an exact manufacture date.

    Rotax has a schedule for lifespan of gaskets,seals and etc......even if they've never been used.
    I think the longest time Rotax has on any of its seals is around 3-5 years....I could be wrong though.

    The only way to be sure is to tear it down and replace all the appropriate stuff so you know the time from when it was overhauled.
