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.

Yes boat is in the water for 5-6 months. No shore power used. Current runs approx 3knts.

I know that he meant electrical current, thats why i posted that shore power wasnt being used.

i just wasn't sure if the fast moving water also was contributing to the problem.

Do you mean just not being used on your boat?? Is there shore power there? Are the boats next to you using it? If it's a stray current problem, it can happen even if you are not using the shore power.

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