How to change impellor on a yamaha 2a outboard?
Dead simple,undo the bolts/screws that are under the cavitation plate and the prop housing and drive shaft will come away from the outboard leg,undo the screws holding the pump body and slide it up off the shaft,you will now see the impeller it will be held on to shaft with small pin/key.Smear a small amount of vaseline around impeller case and twist new one in(its a tight fit) refit rest of bits as they were taken off.
