I have the engine print out, and if says the motor has 98 hours on it. It got a new power head in Feb. And it says 1:58 on the break in so I assume I have 8 hours and 2 minutes of break in left. Is this correct?

I also see TCW-3 listed. I have been reading on here and want to break it in old school. So I would like to use XD-50 for the break in and switch to XD-100. Do I need to have the technician change a setting to XD-100? This boat was a trade in on a new one and the sales guy does not know what oil is in the resevior now. What should I do? Dump the oil and start fresh with XD-50? I don't really want to do that but will if it is best. Is there anyway to tell what oil is in it?
