    Pro XS 250 - new powerhead break in process.

    Mercury 4S pro XS 250. Serial Number: 2B771286

    Hey Don,

    Since this is a new powerhead my plan is to break it in the same way I did when the motor was new last year. Can you give me a quick review of the break in procedure. I have watched a few videos and read the owners manual. However, I would like to see your thoughts.

    Thanks.
