    You 100% sure those ring are seated? If not then I'd wait.
    I'm not sold on full synthetic being worth the extra coin.

    Its your boat and your motor but I wouldnt waste the money. I have had two SHO’s and never used synthetic in either and not one mechanical failure on either....knock on wood.

    I was debating this myself. I've always ran synthetic in every motor I've ever owned but I know its not "necessary" in any of them. Oil level hasn't moved since hour 2 so I'm going to guess my rings are seated
