I have a question on whether or not you really need the large molded black plastic vent tube under the seat? When you pull off the jetski seat, and you have the black molded plastic cross member seat support you unbolt to remove and get greater access to the engine compartment; there is vent large tube that kinda pushes/snap together, connects to the underside of the seat support, and lays in the back side of the engine compartment. Is there an issue with engine compartment ventilation if I were to remove and leave that large tubing out of the jetski? Please advise your comments, thank you!
