    Default water in Bravo 1 drive

    So last year when I winterized the boat I found I had some water in the drive oil. Now that it is spring time its time to address it. I read that you can pressure test the drive and try to pin point the leak. Can I do it with the drive still mounted? What do I do about the remote oil resovoir? Can I pull that hose and just pressurize the system there?

    One other question is the oil did not come out milky but the water was separated and at the bottom. I am guessing the synthetic oil in the drive won't mix with the water the way the old conventional oil used to right?

    We always pull the drive to pressure test and that eliminates the reservoir and also allows us to see if the u-joint seal is leaking. One way for water to get in the drive is if the u-joint bellows is leaking water will fill up in the bellows and go in past the u-joint seal.

    yes pull the drive the front seal on the input shaft only keeps the oil in if water came in through the bellows it would go right in the drive

    Ok thanks guys, I will be pulling the drive. Since I did not loose or leak any oil I guess I would not be supprised if the bellows leaked. I will go down to the lake and tear it appart this weekend and see what I am up against.

    If no oil is leaking out but water is sucking in pressurizing it won't Likely show or tell you anything
    Don't overlook the fishing line behind the prop thrust washer? Takes out water seal but the oil seal stays intact and draws in water there.

    Well pulled the drive this weekend and could not find anything wrong. Like Hullshot says it held pressure just fine. The bellows looked good too. Pulled the top cover and could not see any rust or anything questionable inside. So I put it all back together and will run it this year and keep an eye on it. Can you get moisture inside from condensation?

    No, only if there is a leak.
