    Merc 4 Stroke 60 HP Lower Unit Drain Pug Seal Recommended Replacement Interval

    Yellow Gear Drain Seal 26-830749. How often should these be replaced? Assume if not replaced regularly these could be a source of water intrusion?

    Recommend replacement each time the plug is removed to change lube.

    Yes... they "can" be re-used, but replacement is certainly a wise choice.

    Perfect. Thank you. Yeah, I’ve gotten two seasons out of these and when changing the LU oil, I saw some white streaking out. Just enough for me to think I need to replace these seals.

    I don't use the yellow seal more than twice (new plus one) and always keep spares on hand.
