Thank you for the help!Only parts in contact with water need to have sacrificial anodes for protection. Main engines have no need for them. Parts connected to the engines like transmissions, outdrives, prop shafts, etc. will have them.
Just for clarification, this isn't always the case. Anodes CAN be found inside some engines (a decent number of them, actually). However, Can't Wait's engine does not.Only parts in contact with water need to have sacrificial anodes for protection. Main engines have no need for them.

I'm not aware of any sacrificial anodes on the 7.4 mercs. The only place you find them would be the heat exchanger (if equipped) and I don't believe it has one.Does anyone know if the engines have sacrificial zincs on them? 454 7.4L
Thanks

Ahh! A chance to learn? I did not know that, what type of engines would have anodes? Thanks for the lesson!Just for clarification, this isn't always the case. Anodes CAN be found inside some engines (a decent number of them, actually). However, Can't Wait's engine does not.
My Kohler 4CZ marine generator; in the heat exchanger. Most older American car engines used the thermostat housing itself as the sacrificial anode. Others?Ahh! A chance to learn? I did not know that, what type of engines would have anodes? Thanks for the lesson!
You're right that it obviously needs to be somewhere with water contact. But, for example, my 250 Yamaha has anodes in the head. Again, a water contact area, but still a place one might not normally think of. I want to say I've read that some diesels have them in the engine, as well - but I'll let others verify that.Ahh!

Like with your Yammy, anodes can be anywhere as long as they make contact with both water and the engine, even if that's remotely through a grounding cable.You're right that it obviously need to be somewhere with water contact.
