Reliable marine plugs — I use them every season - Mercruiser 3.0 engine
I use these ACDelco Gold MR43LTS marine spark plugs in my boat (2008 Bayliner w/Mercruiser 3.0 AlphaOne gen 2 engine) and change them every season as part of regular maintenance. They have worked great for me and I’ve had no issues with them. The engine starts reliably, runs well, and these plugs have been consistent from season to season. For marine use, reliability matters a lot, and I like knowing I’m putting in plugs that have already proven themselves in my boat. Used in my boat I replace them every season Reliable starts No issues with performance Good marine spark plug Consistent quality Overall, these are dependable spark plugs and I’ll keep using them as part of my yearly boat maintenance.

These are Marine Grade Plugs
The package will indicate non-automotive plugs. They are clearly marine grade. They fit into my ford just fine and seem to be working correctly.
