My Attwood Aerator 500 Model #4108 has died and I am trying to find a replacement. The problem I am finding is that the 4108 has a 1" dia. inlet but is no longer available. The replacement model 4660-7 has a 1-1/8" dia inlet. Any suggestions on an Aerator with a 1" dia. inlet?

Ayuh,..

The Standard now-a-days is 3/4" for the small pumps up to about 750gpm,..
And,..
1, 1/8" for the larger pumps....

I guess I'd go ahead,+ bring your hull Up to date by refitting the lines to 1, 1/8".....
Or,..
You could shim up a 3/4" pump....

A lot of times when I look for NOS items, I find them on Ebay. They have a #4108 on there now for 29.00 BIN.
