Dwight, What seals went bad? The propshaft seals usually last a long time, unless fishing line gets under the prop. The seals on the water pump base are easily replaceable.
Foot, The waterpump base has a driveshaft seal, a gasket and an Oring, to keep the warter out. I would change those first, since it is way cheaper and easier. Also, make sure the drain and fill plugs have gaskets on 'em.
