Why doesn't my Perkins have any Zincs?

One thing I can't seem to figure out about my Perkins 4.108 is why it doesn't have a zinc. My Yanmar did. The perkins has multiple different metals in contact with seawater, and yet no zinc is designed into the system.....

Pray tell why? I'd like to believe that since I have "one of the most reliable engines in the world" that it's all okay and the British engine designers are really geniuses above all other engine makers. But then again, these are the guys that are STILL using cork gaskets and making an engine that leaks on the show-room floor.

I ask because I just noticed a dripping leak from my raw water pump yesterday. It's pretty green and rusty right now, and my raw water strainer is looking a little green too....

Should I add pencil zinc myself on the raw water side somewhere? I've got lots of exotic custom plumbing (that's all turning green) to feed the engine and the hot water heater. I could add a zinc in there easy enough.

Good idea? Bad idea???
