Re: 2000 Challenger with Mercury inboard engine, operated around Springfield, Missouri lakes, mild winter weather that drops below freezing at time to 10/20/30 above zero over 3 winter months.
How important it is to change the lower end stator fluid and propulsion end stator fluid? And why?
How many in use hours or what time period should this be done?
I read that the concern is "winterizing", to eliminate water build up freezing, so should this be done pre or post winter before the boat goes back into the water for spring/summer? How much water can these units realalisticly develope pre winter?
For this winter all I have done so far was to pull out the battery trickel charge it every 45 days, also added some additive (heat- brand) to the fuel tank and removed all spark plugs, squirted some 30/ weight motor oil into the engine cyinders, then replaced the spark plugs. The engine only has 40 or less hours on it since 01/08 and at that time the stator fluids were changed.
