So I accidentally put ac delco 41-110's in my boat with the mercury 5.0 mpi engine. I got the part# mixed up with the correct one 41-101 (41-993 is also an alternative). I haven't started the engine, don't plan on it and I've already ordered the correct plugs but I've been searching online for the specs for the two plugs to see if the 110 will work. Obviously if I can't determine that I'll swap them out, just thought I would throw this out before I swap them to see if anyone knows. I tried contacting ac delco customer support and they said contact a dealer...not much help. The best I could find on specs were attached to order placement with other companies...

Heat range is way off, I wouldn't run it.
