Does anyone know if the engines have sacrificial zincs on them? 454 7.4L
Thanks
 
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.

Thank you for the help!

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.
 
Assuming you're lake-water cooled, the anodes on the outdrive will take care of the engine.

Ahh! A chance to learn? I did not know that, what type of engines would have anodes? Thanks for the lesson!

My Kohler 4CZ marine generator; in the heat exchanger. Most older American car engines used the thermostat housing itself as the sacrificial anode. Others?
 
Heat exchangers would be obvious as they have water contact…that’s very interesting @Nater Potater about thermostat housings, I did not know that. Again, to my pea brain that makes sense as the thermostats are subject to contact with the cooling water…. Good catch!

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.

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.
