2001 Merc 25hp maintenance

[iMacattack]

I have a 2001 Merc 25hp. pull start.<br /><br />I want to do the scheduled maintenance myself. I checked-out the proper manual for my motor from the library, but it really doesn't get into the parts and processes for a 100 hour tune-up. What should I check, change and replace?<br /><br />Thanks<br />Jan
