Preheat oven to 350°F (175°C).

Grease and flour a 9 x 5-inch loaf pan.

In a large bowl, sift together flour, sugar, soda, cinnamon, salt, nutmeg, and ground cloves.

Make a well in the center of the dry ingredients.

In a separate bowl, combine melted margarine, beaten egg, pumpkin, and water.

Pour the wet ingredients into the well of the dry ingredients.

Mix until just moistened; do not overmix.

Pour the batter into the prepared loaf pan.

Bake for 1 hour and 10 minutes, or until a wooden skewer inserted into the center comes out clean.

Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
