I need to repair replace or upgrade my sea water pump. It has cracked the housing and spewing water! It seems to be plastic and I would rather it not be but what are my options

You can get one of these. You will also need to get 2 of the 1 1/4" fittings shown down below it.

Or one of these. Not so sure of the price their showing though because most other places these pumps are over $500.
