Currently using the mercruiser aluminum anodes as they recommend. I'm only getting half a season out of them. does that sound right?

Should I switch to zinc ones?

Do you trailer or keep the boat in the water? If its in the water it sounds like your marina has a stray current issue.

Stray electrical current can come from anywhere, it doesn't hae to be from you boat to eat your sacrifical anodes.
