Re: Impeller replacement Merc 5hp
Around here, any stoppage involving a small hole should be checked to rule out mud dauber infestation. These pests will fill any small hole with their mud nests, spiders and their eggs/larva. I have to clean out the discharge hole on my little British Seagull outboard every spring and as necessary throughout the summer.
