My diesel Yanmars have numerous zincs. While not as wide as the factory 454's, they are taller, and thier outboard sides are under the deck, not a hatch.
Even though I fresh water flush after each use we still have to replace the pencil zincs about every 18 months, especially the one at the bottom of the fresh water cooler.
The Yanmar 6LP has zincs on the heat exchanger, oil cooler, intervooler and fuel cooler.
To lessen the cussing and make this job go easier I added two rotating cover hatches to the deck to ease access to the difficult ones.
In my case these round access hatches are located under the wetbar or Lbench seating and are not even visable unless the deck is taken apart.
This way I can replace those zincs from the cockpit floor, instead of squeezing myself into the aft corner of the engine room. (which is getting old and not fun, especially on a hot day !) This is especially helpful with the heat exchanger bottom zinc, which is easier to change when removing the hose.
Also, FWIW that same zinc is far easier to replace if you grind down the head a bit.
