I didn't get the marine version of the plugs, but I've bought these before and had no problems

3/5

I have a Mercury 250 efi and I use them. Because it's an older model, I have to replace the plugs every 8 to 10 years. br>br>Well, the last time I bought this set, I DID NOT receive the marine grade plugs, but rather the regular ones. br>br>Well, the last time I bought this set, I DID NOT receive the marine grade plugs, but rather the regular ones. br>br>Well, the last time I bought this set, I DID NOT receive the marine grade plugs, but I needed them, so I used them anyway, and two of them died after about 8 hours of use; however, it was my fault for not returning them. I placed another order, and if they are not marine grade, I will return them. br>br>I'm writing for anyone else who might get regular plugs instead of the marine ones: RETURN THEM, they're not the same.

5 of the 6 Champion QL77CC plugs I ordered had zero gap, meaning the ground electrode was smashed into the center electrode

3/5

This led me down a $200 rabbit hole of replacing ignition coils in an attempt to resolve the outboard motor's apparent rumbling. I'm hoping the motor did not sustain any internal damage.
