When I fish thru out the winter I will go as far and disconnect the water hose on the speedo and water pressure gauge. If the gauge don't drain out it will freeze up and break and be another expense.
If you have an air compressor at home , use a short blow gun and hold it tight against the pee hole on your motor and blow into it . This will force the water out at the intakes on the lower part of your motor.

Fish like hell, make up lies.
