"Merc part number 46-43024A7 is the complete kit - base, cover, impeller, gaskets and bolts - don't let your heart stop when you see the $122 pricetag.

It's pricey because it replaces the original plastic parts with aluminum, so if you have "all original" it's worth changing it over.

Otherwise an impeller and the seals and gaskets (sold individually) would cost 40-50 bucks and any Merc dealer can look up the individual part numbers if you go in.

Personally, when it comes to the waterpump I stay away from aftermarket stuff. Since a bad part can toast your motor I always use OEM....."
