So sad... only 2 choices:
Do nothing (always popular), or spend $75 × how many?

No engineers here? Not sure which side of the boat hull to put the patch on?
Since there isn't any positive pressure unless something goes wrong (the complete opposite of a blower manifold) a holesaw and a big piece of duct tape works just fine. Fails instantly with any cough (which the small panels won't do until their pre-set is reached).
Wonder why they put stuff down a demo hole after the dynamite? Because the expansion in the first few milliseconds is very important.
Just imagine the facial expression when a sneeze wrecks the carbs, dents the hood, bends up the linkage and tears the fuel line off!!!

Well, except for the annoying comments of the skin-packaged billet color-anodized speed equipment enthusiasts...
