2002 Yamaha 225hp 4 stroke.
Prior to any work I had a full tank of fuel - I added some Yamalube Ring Free, Marine Sta-Bil.
1. Removed prop, Drained gear oil with drive tilted
2. With drive level refilled gear oil with Yamalube gear oil - filled from bottom until gear lube come out oy top hole steady with no air.
3. Arranged muffs with "Y" fitting.
4. lower water intake covered with tight muffs.
5. Short 1/2" hose connected from "Y" to Flushing connector on starboard side of engine (per dealer)
6. Removed top silencer cover
7. Removed intake plastic covers
8. Removed oil filer plastic cover
9.Turned water on fully open- waited 3 minutes to fill engine
10. Started engine
11. Waited 45 seconds and "Tell tale" started "peeing"
12. Engine running at idle for 15 minutes.
13. Spraying fogging oil for 5 sec in each throttle body (3 times each)
14. Engine smoking
15. Shut off engine
16. Removed Spark plug cover
17. Removed each spark plug & wire
18. Sprayed fogging oil in each cylinder for 8-15 seconds.
19. Re-installed same plugs
20. Re-install spark plug cover
21. Drain oil with electric pump
22. Remove oil filter
23. Add 6qts of Yamalube 10w-30 oil
24. Replaced oil filter with Yamaha filter
25. Greased spline
26. Greased hatch hinges
27. Greased linkages.
28. Connected a air line to the flushing attachment.
29. Blow air through the flushing attachment.
Tomorrow I will clean the fuel filter and inspect the zinc's.
My dealer insists that antifreeze is a waste of money and that the engine is self draining.
Does all the water in the block drain regardless of the thermosats being open or closed?
Is there any chance that some water may remain in the engine?
Thanks all!
