Alright. Quick update and some questions. I emailed bob(flyingscott) for the impeller and needed to know if it was a rotor or a impelller. I assumed rotor from schematics. Upon taking lower unit off, i discovered the impeller is made completely of aluminum and has 6 fins. Hmmm. Ill attach pictures if i can.
So, the impeller looks fine. Maybe this isnt a scott atwater. From a video i watched, it looked like the water exited from a hole below cylinder head. Turns out this isnt a hole and is part of the casting. I can blow air through the impeller hole and it exits from another tube by the lower unit. I can hold my finger over tube end and can see a little water coming out by head bolt. Very small amount. Im assuming it is pumping water at this point. Does any of this sound correct? See pictures and i can explain further.
There is no graphics on motor. I do have some serial numbers though.
#462 stamped on motor casting. 460-38671 stamped on by mounting bracket. All help is much appreciated.
