    question about pitting on lower unit

    was noticing some pitted areas on my '98 90ELPTO lower unit...there are some areas here and there but it looks to be concentrated around the drain, fill and vent plugs. why is this (around the plugs) and what causes it? and how long does it take something to become pitted? thanks

    acetone to speed drying

    You may have read in another thread that I am dealing with a thruhull fitting (livewell drain) that was letting water into the transom.
