My Vectra L1 seized up and while trying to take it apart for a vinegar bath the head of the propeller broke off. I will have to remove the propeller shaft later but need to find a replacement. I am not going to purchase an entire new pump. I looked on BRS and the EcoTech website but cannot find a replacement. Does anyone have any advice on where I can find this part? I have a Mag 9 handling the load for the time being but it is undersized for the task.
