The exhaust on the 32 open was changed in late 2004. The exhaust out the back was changed to below the water line with  pressure relief exhausts on the side. I had my boat converted by the factory at that time and it solved the problem which was a station wagon effect issue. Without the modification the boat does draw CO into the helm with the center windshield vent open. Close that window and the problem is less severe. Running with the drop curtain down and fully closed also keeps the fumes out.

SB1,
I'm not sure what you mean by "the exhaust on the 3200 open was changed after 2004".
My boat is a 2007 and the exhaust comes out the rear.
Can you clarify?
Thanks
Walker
