You can use ordinary power steering fluid from the auto parts store.

The dealers here want an exhorbitant amount for a container of
Durapower Fuid for my Penta Sterndrive.

Anyone know of a cheaper subsitute? Mine seems to be leaking
somewhere and until I find/fix the leak I can't afford the expensive
stuff.

Thanks!
