Save my weekend! I finally found an impeller but it needs a little help and Jack at MPD is booked up.
It's a Jacuzzi aluminum impeller and in a few hours I'm going to a buddy's shop to get a nick in the blade welded/ filled. Nick is about 1/8" X 1/2". Impeller is stamped PD 4100 MM.
Does anyone know what kind of Aluminium this is? My friend is a welding engineer so I'm sure he is competent but he is not a boater and is asking what alu.
Thanks in advance!
