The drive shaft on the Evinrude 1958 25034 35 HP. seems to not be turning and no water is coming out. I need a drawing of how the top of the drive shaft is fitted and the part numbers I need to order for repair. The water pump was replaced two weeks ago and was working fine. Thanks
 
There is a spline on the end of the driveshaft.----Fits in a spline in bottom of crankshaft.---Post picture of spline on end of the shaft.
 
Ther is a groove around the splined area of the drive shaft, for an o-ring. The splines are to be lubed with a light coat of grease upon assembly, and the o-ring keeps water out of them.. If water does get into them, the splines will rust away from the steel crankshaft. The drive shaft, being stainless steel doesn't rust. Likely somebody long ago has left the o-ring out. Lack of a 10 cent o-ring results in loss of the whole motor, considering the cost of a new crankshaft. Sad.
