    Depend on the driver. You should get around 500 hours on a well kept 525 and slighly less on the 600 due to the SC. Both are very good turn key motors, but don't blow one the cost is very good too.

    So doing the maintenence makes themm last longer?? LOL The 50 hour service on my SCi/XR is going to be about $300, not counting pickup and delivery. That's a minimal (in my experience) service, oil changes and inspections, according to what the Merc book says, so if they find anything in all the inspections, there will be additional cost. The supercharger belt on my Mini was $32, I'm just guessing that the 600's will be well over that.
    I heard of a Mercury Racing program that swapped out the engine/drive for a rebuild at 100 hours for megabucks. I thought that was rather low hours for a rebuild.

    I've heard of the same "re-fresh" program that you are talking about but I don't know if they do it on the smaller motors like you are talking about. I thought they did it on the 1200, 1075, and 850. I maybe totally wrong and it would be cool if they had that program on all motors. The other thing that would be cool to know is what happens when a 525 / 600 get's to 500 hours? Do you take the motor apart and re-sleeve it or bore it out and how much would it have to have like a certified Merc shop basically rebuild it. But if they re-built it it wouldn't really be a 525 or a 600 anymore because they would have to bore it out, is that right?

    That's the 1050, whole different ball game.
