38/40mm carb based gasket (I-body carbs)

This is a carb based gasket gasket for I-body carbs found on Seadoo 717, 787, and 657x engines.  Can also be used on I-body 38/40mm carbs for other brands. 

If you have a Seadoo jetboat and your thick blue gaskets are still in good shape, you will want to reuse them as those are discontinued.  The thick gasket is to prevent vapor lock (excessive heat transfer that may vaporize fuel)

If you can’t reuse your thick blue gaskets, you can stack 4 of these green gaskets together. 

These green gaskets are made of a high aramid fiber with a nitrile rubber binder, asbestos-free.
