Corroded Bilge Pump

Well, there is a pump under there. This is a 25 year old Whale Gusher 10 from Scamper's cockpit. These pumps are made of aluminum and Whale recommends flushing them after use. I really don't like that thought for a bilge pump but the alternative is a plastic Titan.

I talked to a guy at Whale and he strongly recommended staying with the metal pump. Since the plastic pump would also require different mounting holes I guess I'll pony up the extra cash and get a new Gusher vs. the plastic Titan.
