Is it legal to have zoomies coming out through your hatch????????

Enlighten me as to what Zoomies are???

You cannot have a non-water-jacketed header in an enclosed engine compartment. No hatch- a water injected zoomie would be legal. If you are talking about something like the CMI tractor header going through the hatch, there's no restriction that I'm aware of.

Over-the-transom, water-injected headers- as you might find on a jet or v-drive- like a drag boat.

They run Zoomies on Flat bottoms , but like was stated not on a closed hatch set up , Definite fire hazzard. Seen a guy when I was kid put headers on his cabin cruiser, looked good, but didn't last very long burned to the water line.

There is a set of the CMI tractor headers in the classifieds

closest you can get is CMI tractor pipes. its a header that collects down to a single water jacted pipe that exits straight up or slightly back. they are legal water jacked but the noise is a problem, you would never pass a level test and to be perfectly honest would be WAY to loud for a pleasure boat.

What about some of the headers I have seen on a few Outerlimits that go out through the hatch? ie.. XXX

How are they getting around the noise laws? I have only seen pics, but did not look to me as if they have anything to keep them quiet?

thats what i am talking about like the ones in the classifieds...........tractor pipes i guess

Here's some real four pipe water jacketed Zoomies.

Legal by who's rules?

anybody know anyone who has a pair of water jacketed zoomies for sale???
