Mercury ProXS 115 - How To Change the Spark Plugs

In this video, we look at how to replace the spark plugs on our ProXS motor. I cover some tips for how I replaced my spark plugs recently and also discuss some interesting information about NGK Spark Plugs.

Extremely informative vid. Doing this for my Merc 90HP for 300hrs. shortly and this really helps. Thank you!

Buying a 115 ProXS. Your videos have been thorough and informative. Thank you for doing such a great job educating me!

[@PaulsOutdoorAcademy]

Thank you very much for your kind comments. :)

Really appreciate the info, I have the same engine and serviced it for the first time this fall. That bottom spark plug really drove me crazy.

[@PaulsOutdoorAcademy]

Isn’t that crazy, how hard it is? You know what else is very difficult is replacing the fuel rail fuel filter. The one located in the bottom of the fuel rail. You pretty much have to remove the lower cowling. If you ever need that vid let me know. It’s on my channel too.

@@PaulsOutdoorAcademy I haven't had to do it yet (thankfully) but I did watch your video and Im dreading the day i do have to do it

[@PaulsOutdoorAcademy]

@breakfastboyboating it’s all good. Hahahah

The plugs that came out were .28...the new plgs were .30 and adjusted to .32 on my motor.

[@PaulsOutdoorAcademy]

I wish I had checked all the old ones but I definitely checked the new ones. I also bought a feeler gauge and like it much better 😃

Glad you liked it!

This was a great video! The step by step and tips were awesome! I'm surprised that NGK don't have the plugs gapped already. Did you not put dielectric grease on the plug because the factory stuff was sufficient?

[@PaulsOutdoorAcademy]

It seemed to me like there was quite a bit still there so I just used that. Next time around I probably will 😎 thank you for the compliments and questions!

[@AmericanPatriot-jj7nh]

That is a fancy spark plug remover lol. I didn't know it but I have a set of those😂😂 actually a good idea!

[@PaulsOutdoorAcademy]
