    Plugging lower unit holes

    I have a 250 pro xs with a stock 1.75 lower unit. It has holes up the sides and in the front nose. How many holes on the side can I safetly plug up so I can raise my motor higher ?

    When you talk to Don at European he will explain how to install them. You can pull them up on Mercury's web site in a round about way, I gave you the part # off of mine that I purchased from Don.

    Part # 17280A2 is for high speed inlet covers but I think these are for over heating not blocking holes.
