Location: Downers Grove | Trying to save a few bucks and wanted to see if any of you guys do this yourself, and what steps you take to do so.
Thanks

| I run Stabil the last couple tanks of the year. Also, Merc Quik Kleen all year. When you put the boat up, change the lower unit lube, drain the water separator under the fuel filter and plug in the charger. Don't forget to look at and repack your wheel bearings and replace the seals.
If you are storing outside, make sure you have the motor(s) verticle so all the water drains. Make sure your livewell and bilge pump lines are empty.
One more important thing. DO NOT fog an OPTI.

Location: Hayward, WI | Search for Bass Boat Centeral and look in the Mercury forums, very good write up on Opti Winterization. You should get some extra oil in the motor, you can pull plugs and put a little 2 stroke oil in each cylinder, or take it to a dealer and they can run the oil pump to pump extra oil into the motor to coat the internals. Also a good idea to put a couple of drops of oil in the compressor inlet. |

Why not? I don't own an opti. Simply curious |

Stabilize your fuel, run the engine under load for at least 15 minutes to get the stabilizer up through the system.
Change the gear lube
Change the fuel filter
Change water separator/filter
Inspect belt/tensioner
Grease all the pivot zerks
Check mounting/steering fastners
Check engine mounting (and jackplate) hardware torque
Check torque on mounting/steering fastners
Check steering hardware torques
Check air compressor filter (if equipped),
Determine whether water pump replacement is needed & gaskets
Inspect/test thermostats
Verify no faults with DDT or Computer Diagnostic System
Remove and inspect spark plugs (replace if needed, or perhaps based on hours/age), and if you like, add about 1 teaspoon of oil (same thing you run in the oil tank) to each spark plug opening.
Remove prop, check for fishline or hub damage, grease shaft and retorque prop
A good, careful "visual inspection" of the entire engine.
Spin the engine "clockwise" by hand a few revolutions, reinstall the plugs- and then park the engine in the "full down position" for off-season storage.

Because the fuel is injected direct into the cylinder, it does not go through the crankcase like a EFI or Carbed motor. If no fuel goes through the crankcase there is nothing to "wash" the fogging oil out and it can gunk up and stick the rod and crank bearings. It can also plug the oil recirc system. |

Because the fogging oil will harm the injectors, and lack of fuel equals lean condition, and that would not be good.
As for removing the plugs, I do this only to check the condition of the plugs. I don't put any oil in the cylinders and rotate the motor. It's a waste of effort, and can cause fouled plugs the next spring. |

How is this possible? |
