'59 Sportwin Model 10018 10Hp Drive Shaft Replacement

[bassin'frog]

Am rebuilding this motor to replace my Fisherman 5.5...pulled the driveshaft and the bottom half inch that sinks into the pinion is shot! Can't find a replacement. I've looked on iBoats, Marine Engine, Vintage OB's, Wholesale Marine, eBay, and one or two others. Was wondering if I can get a shaft with splines on the bottom and replace with pinion with a pinion that requires a splined shaft? Any help would be greatly appreciated guys..

I have a strong feeling that the shaft is only a small part of the problem. Those units are notorious for wearing out the pinion bearing/shaft, especially if it has ever been run with water in the gearcase. And when it does, the pinion gear moves to one side due to the bearing slop. That in turn causes stripped gear teeth.

All this to say, check that bearing for slop. And if it is worn, you need more than just a drive shaft.

Once I saw the damage to the drive shaft I pulled the whole L/U apart and checked it over for other damages, much to my surprise I found none..... everything is in excellent shape. Now, if I can just find a replacement I'll be a little happier....
