I have a 1990 Marlin Aries 21 foot jet boat.The tag on the Berkley pump says Model #12jg-a-ao Impeller A-a0.What is the-a0 mean?It has a 454 motor in it.

I believe you are looking at a Berk "G" pump (split bowl) with an "A" cut Aluminum impeller. At least that is what it was when it left the factory.
