Curious as to what everyone else out there does to take care of their outboards. Here is what I do for my twin 2000 200 HP Yamaha 0X66's. I probably average about 80 to 100 hours of use per year.

Bi-annual
1. Replace water pumps/impellers

Annual
2. Replace lower unit oil
3. Perform tune up with certified Yamaha mechanic

Winterize
4. Put stabilizer & ezorb in my fuel tank
5. Fog the engines
6. Pull the batteries and electronics from the boat

Semi-annual
7. Replace sparc plugs
8. Follow the dunk method of using Seaforam to decarb my engines
9. Replace the external Radco 3213S fuel filters.

Ongoing
9. Use rung free every other tank of gas.
10. Check the bottom of my radco fuel filters after the end of each trip to make sure that i don't have any crap/water in my fuel filters. If I do, I drip it out.
11. Only use Yamalube oil for my engines.
12. Towards the end of each boat ride I try to briefly run the engines @ WOT to blow any crap out of the engines, as well as to make sure that my RPM's and the like are fairly consistant with the last time that I ran them WOT.
13. Run fresh water through the engines (ok, maybe I don't do this everyone time, but often enough).
