Carburetor Question
Can you cover the carb when the boat is sitting awhile?
I ask cause when I cover it, the fumes build up a bit under the cover

Why do you want to cover it?
How are you covering it?
I’m assuming you are trapping fuel vapor that is evaporating from the bowl.

Based on you other post
"I have a 2006 1800 MX
3.0 with Alpha one Gen 2"
Is the flame arrestor in place? Engine cover installed? If yes to both that is all that is required. Where is the boat stored, outside or inside?

I would not do this as condensation may form under the plastic.

Are you talking about covering the BOAT or covering the Carb?
In your first sentence the subject is "Carb", therefore the pronoun "it" is referring to the carb. Later you mention you want to keep dirt and sun off of "it" (The carb?). Otherwise, why would there be sun shining on the carb??

Turn the blower on after you remove the cover, it will remove the gas fumes, (That is what it is used for.)

shrew/Don in post #6 the OP states
"cover the carb with plastic while the cover is on boat"
which is pretty clear he is referring to covering the carb with plastic. I don't see any benefit from doing this but would also be concerned condensation may form under the plastic and drip into the carb.

I'd add a 'ridge vent' to the cover. If it's sealed that tight to keep fuel vapors in, its collecting moisture too and you'll be asking for a mold/mildew issue. Any canvas shop should be able to add a vent to your existing cover fairly inexpensively.
For guys from up north, this is why we put the vents on our shrink wrap during the winter months. Having airflow under the cover is good while keeping out the weather.

+1 on Mike and shrew.
Maybe I am just getting old and grouchy,but it sounded to me he was worried that the fumes could be a problem. When it is common to have some fumes, especially in warm weather.
