mounting the air scoop

ok so im just looking around and some guys have the scoop backwards.... is that a reason for this??? or is it just looks???

2 reasons mine is backwards...number one is I have taken a couple of accidental roosts from other boats...ok ok one was intentional...number two is I dont run a flame arrestor

sooo if you mite "accidently" get roosted, mount it backwards.... what about preformance??

 there is no ill effect to performance if you mount it backwards. I also run mine backwards

Actually never noticed a difference at all....i might add I think they look better fwd

I agree w/ Nordie, they look better forward.
Years ago I had a friend who ran the scoop forward w/ no spark arrestor. Every once in a while it would send a fire ball right up the center between the 4 of us. We always leaned to the outside when the boat was being started.

Less engine noise with them backward too...

It IS possible to get roosted with them backwards........I did it to Nick unintentionally. 'twas ok, but coulda been bad, 

How it works out is this. Legally, if you have flame arrestors, OK to run 'em either way. Without flame arrestors, they HAVE to be faced away from the engine compartment on open engine boats. Closed engine compartments, you have no choice, they gotta be there.

In practice, Circle Racing boats run 'em that way because theres a LOT of water spraying around everywhere, at least that's what I think. Drag racers don't have this issue, really.

FWIW, my honest opninion is that while it takes around 10-15 HP difference to feel it "seat-of-the-pants" in a street or drag car, with NO OTHER CHANGES, it would take at least a 50 HP difference to feel it in these jet boats. You're not gonna see that with which direction the scoop is pointed.........

I always wondered the same thing until I drove my boat with it forward and with it backward;

1.  It is very noisy facing forward.  When the secondaries open, sounds like a supercharger or whistle blowing in your ears.  Facing towards the rear, it is not so loud.

2.  It is hard to keep it facing forward when going in rough water or fast.  It tends to want to move to the left or right, but if it starts facing backwards, it stays that direction.

3.  Water entry into the engine is a concern when facing forward, but I never had a problem with people spraying me.

As long as you stay in front of Ray you should be O.K. 

oo so they turn??  that would suck.. and look funny if you saw a boat with the scoop to the right or left

Yeah, that HAS happened more than once,  N8, Gil, Nick, and I think I got Skip once.

They shouldn't turn if you have them mounted correctly.
