out at Lake Pleasant, Arizona in a wet slip. I would like to find out the
proper recommendations for leaving the boat for a week at a time in the
Should the lower unit be tilted COMPLETELY out of the water? Or should I
leave it down in the water? AND Why?
What are the pros and cons to each? When and how often do I need to flush
the system with a hose?, and how is this done? What extra equipment do I
Since you are in fresh water, leave the motor down when you are gone. My reasoning is that your prop will be better protected from other boaters backing into and out of the slips near your boat.
Unless you run the motor aground in mud, or use it in some kind of strangely polluted water, you should not need to flush it. Again, you are in a freshwater lake, so there is no reason to flush it for corrosion protection or the like, if you were operating in saltwater.
Having said that, you can buy a motor flusher device at Wal Mart or any boat shop for a few bucks. They are commonly referred to as "earmuffs", and attach to a garden hose. You then put them over the water intakes, turn on the water, and start the boat.
