replacing spark plugs

AC Delco 41-101 platinum , gap .040” 1.02mm

Are these the correct spark plugs for a 2011 indmar 350mcx , or are there different models/brands you can use.
also where is the best online shop in the states to buy them from.
regards

Hi .. For my 2008 MCX the 41-101 was an iridium ac delco plug that you can get at Napa .. Gapped at .060 from the box. I am guessing that is the same for you. You can also get them at your dealer or skidim.com.

The platinum plug works well also .... but I did some reading and our engines have CATS so the Iridium was preferred for higher temp application.

How often do these need to be replaced? 2008 MCX with ~ 350 hours. Thanks!

I replaced mine at 200 hours along with rotor & cap, old ones were still going strong though. Some will tell you every year, I think that's a bit MCOCD though.
