I wouldn't run these in a enclosed engine capartment. They are just water injected headers and get hot.

Oh and I tried to stick a earth magnet on em and it won't stick any where 8)

wouldn't recommend using with a motor cover just as hot as basslets with no air flow

What is the difference in these and the lightning headers? Many guys run those with a hatch. Just thinking of ideas, thinking of getting rid of my logs. But not willing to give up the hatch.

lightning are a jacketed header. think of a pipe within a pipe. the cavity between them is completely filled with water so the outsides of them are cool to the touch. then at the veeeery end the inside pipe ends and the water and exhaust mix and exit out the back of the boat.

Lighting headers are a pipe with in a pipe water jacketed. Only get warm
These are water injected only one pipe so they get hot. Water only gets injected over 1500 or more rpm at idle they are extremely hot
Not a good idea to run them under the hatch due to the heat that they can create.
My hatch is only on cause I'm converting from logs to water injected headers when I'm done the hatch will no longer be on.

Did the thread pattern match for the header injection connection? Or did it need to be altered in any way?
You have a photo?

I see, thanks for the clarification. That's a big difference.
