- You will need to use your existing petcock drain plug (The one that would have the wings on it) for the plastic fitting still installed on this.
- This has the water fitting for the PORT side, not that you couldn't switch it, but they are sometimes hard to remove when they are the brass style.
- Generally found on various MerCruiser 3.8L V6 Models 1983-1984 & 4.3L V6 models 1985-1997 and possibly others. Some point in 1997 they changed to 1 piece manifolds that had the riser on them as well, they looked drastically different than this one. Check to see that yours look just like this.
