Finding Oil Pump for Mercury Sport Jet

[Jam]

I had an idiot light and buzzer go off on the Mercury 2001 Sportjet 240 EFI inboard engine. I figured [the engine oil] pump quit after seeing the two-stroke oil disappear from behind me. I [cannot] find a pump anywhere on-line. eBay has one that says it fits an array of Mercury engines of150 to 250=HP. No way to know if it would work. Can anyone lead me to an oil pump? Much appreciated.
