Mystery Fuel Pump

[Fastjeff57]

I got a basket case OMC given to me that I'm trying to identify. It's a two cylinder looper, probably a 1980s 50-60 hp. It's pre-thermostat, that helps a bit, but I need to get closer before ordering any parts. It has this strange fuel pump on it that is different from any other I can find going through parts diagragms. (See photo--sorry for the crappy resolution.) The 'normal' pumps for this motor have a trianglarly pointed end where this one is rectangular.


Thanks,

Jeff

PS: Also, looking for a junk driveshaft for it. It's 5/8 " OD with at least 14 fine splines.
