This is an I/O motor 280hp. My boat mech split and i have to do a few things to accomplish before the season. I need to replace the impeller and do a gear lube. This motor is on a 1999 Chris Craft Express Cruiser. Can someone please provide a link to some instructions on how to perform these 2 functions. Also is there any other maint you suggest before i put it in the slip. I have already done a oil change. Thanks for the help
