Anything special I need to do about boat

[Ray]

If you take the boat out of the water and leave the outboard all the way down,
most all the water normally runs out the motor. You shouldn't have to do anything,
but if you want to, you can go to West Marine and get the pink environmentally
safe antifreeze for winterizing boats. Remove the thermostats and pour some in.
This will push out any water out the bottom of the motor and replace that water.
