Any one install a Hot dogger on their boat?

We use these on the exhaust of our sleds for afternoon snacks, install them on the exhaust. I'm wondering if the manifold on a boat would get hot enough to cook anything being it's water cooled.

Anyone install one of these on their boat for an afternoon snack out on the water?

I'm thinking the downslope on the riser would work best:
