  • Mercury 4 stroke break in procedure-Boscoe

    Hope everyone here is healthy and happy!

    You posted concerning this topic either here or on TOS. The last time I tried to access an operator manual on the Merc site, it required a serial number of motor. A friend has the bug for a new boat. Offered with a 2023 F250 4.2 liter. I mentioned that Mercury break in was a tad more strenuous and IMO, better. Assume, guess and hope, the procedure is fairly standardized for their larger displacement motors. Would you be able to access?

    Might be fun to post this over at TOS just to stir up some crud.

      Hey there. How have you been?

      Here is a snippet from a Mercury Owner's Manual that I got from the innerweb. Dated 2016.

      I agree with you. If I had a new Yam I would use the Mercury procedure.

        Thanks Boscoe! Hope all is well NW of ATL. I hope to be able to visit again and eat some of those incredible Martin’s biscuits for breakfast.
