The aerator went out in my boat yesterday. It is an Attwood mini King 500. I've been looking and it seems they don't make them anymore. The part number on it is 4105A. Does anyone know which of the Attwood Tsunami pumps will replace it?
Remove it and take it with you to the boat store and just match it up as best you can. Shape, fitting size, volume, mounting. I'm sure you'll be able to find something that is a very close fit.
