Collapsing the bent drive shaft tube will let you know if that projection above the pump plunger hole is for an aluminum alignment pin. It would be easier to weld the anti-cavatation ear by the water pump hole rather than the skeg because it is farther from the oil. The keg will not take any abuse. From what I see, ¾ of them are broken off. Running through sand is very hard on the piston of the pump. If it wares through, solder a copper penny over the end. . . 😉
