So does use of an AM hood require breather tubes through the pole bracket?

I don't know of any aftermarket hood (for an OEM hull) that doesn't have hood breathers.
Some aftermarket hulls now come without hood breathers (Rickter XFS/XFR/Ninja and new EVO's, Footrocket) and other aftermarket hulls are shipped without the hood breathers installed (Superfreak).
If you do forego the hood breathers, the pole breathers better be big enough. I don't think the XMetal breather tubes are big enough, especially with all the stuff you gotta cram in them.
RRP should be fine.

rrp adds a hood breather on their comp skis...
How are they doing that with the XFS style hood?

I was also wondering about engine compartment venting for fumes.
I am under the assumption that in the stock set up, the air enters the front holes in the hood goes down the first tube and up the back tube to an exit vent. This would provide fresh air at the entire bottom of the compartment if there was forward motion of the ski. Am I correct about this?
Then, would a AM hood without the pole bracket vents not provide this venting because the air inlets are at the tray? Or is there something else that takes care of venting with the AM hoods? Or is it not considered important enough to worry about?

So no venting needed?
your over thinking it, air in smoke out. the littl vents/breathers are to prevent fumes building up in the sealed hull while stored for a period of time which can then combust if you say walk out to make sure your ski runs after not riding for a month and you just hit the button to crank it over

I would not have believed it , but do a test .... Put your hood on without it being strapped or latched . Then start your ski rev it a few times and watch your hood suck down on the seal. Not saying all hoods will do this but my older Berky hood does and so does the hood on a matrix. Scott S showed me this test. I don't know if it really affects proformance ,but it gives you an idea of how much air these motors process..... I think Art told me once you should try to have a minimum of 1.5 times the carb volume.
