Plug read, opinions needed

Not bein a smartass at all but just throwin this out there. You could have tried some hotter plugs by now "just to try it" in the time you've been battin it around here. You said you have 7s in it now? On the NGK plugs, aren't the plugs hotter going down in number? I think that's right. I'd try 5s and see what they look like. It's not like it's a big expense and it takes almost no time.

Rusty, this engine was run and tuned on the dyno during one full day. The engine is now on a pallet mocking me waiting for me to install it in the boat. I pulled the plugs after the last dyno run to get a read on them. Trust me there will be some testing done after it’s in the boat, but that is impossible now.
