I think I went pretty well by the book for my engine break in period. I put 10.5 hours on the motor breaking it in. Am I able to do the fun stuff now like knee boarding etc...? Anything else I should do? Another question. Would it hurt anything to change out the lower unit fluid now? I think it's called for at 20 hours but I don't mind doing it both times if it would benefit my motors lower unit. Thanks, Sean
