I bought a lower unit for a 200 HP Evinrude 1997 that had been "rebuilt". UPS brings it and when I turn the drive shaft it sounded a little rough. Dig into it and find out the drive shaft is broken at the pinion gear. I am trying to get the pinion gear out but have nothing to keep the inch I have left of the drive shaft from turning. I did some research and read where I can put it in forward gear, hold the 7/8 wrench on the nut and turn the prop shaft to get the nut free. Long story short - can anyone tell me the part number of the prop spline wrench I need? I tried just turning it with a prop but did not have any luck.
