I do not have specific information on 8.1 Cruisader Pumps, but here is a tip I learned years ago.
Raw water pumps have weep holes to let you know when the pump seals fail. Vessels that sit for long periods of time can develope minor corrosion on the shaft up against the seal inside this weep hole. When you fire up the engine the corrosion chews at the edge of the seal. The more damage to the seal, the further inward of the seal the corrosion develops. Eventually the seal begins to leak.
Tip: Pump the weep holes full of synthetic silicone grease. The synthetic grease won't damage the seal and it keeps corrosion from developing on the pump shaft.
