[QUOTE="kofkorn, post: 389905, member: 7076"] I've changed water pumps on several motors that are exclusively saltwater use, with no chance for flushing (Kickers, dinghies) The large majority of the lower is usually in good shape. However, the area directly under the waterpump, right at the driveshaft seal, is usually heavily corroded. This is one of the areas that doesn't tend to drain on it's own. Also without flushing, there tends to be a significant amount of corrosion and salt build up in the cooling channels around the cylinders. If you have the ability, I would suggest you flush as often as possible. If not, keep an eye on your cylinder temps every once in a while. If they start getting too high, you will need to consider pulling the head gasket and doing a deep clean. [/QUOTE]
