I want to keep the stock hood liner, glass off the front 6 vent holes and the two top rectangle vents. On each side of the hood latch, about an inch away each, I want to cut two 1 1/2 inch diameter holes and do the same in the back of the hood liner. Then I'll connect the holes with pvc pipe or some other tubing. Could you tell me what you think?
Super Jet Will this work as my SN hood mod?

I think that it will still be an extremely heavy hood.
That liner and all the crazy green goop is where all the weight is, rip it out and make a new liner.

Ok thank you guys. Though I'm not even factoring in weight right now, I did choke my engine out last year experimenting with duct tape on my hood vents. I forget the exact diameter of the hoodliner exits in to the hull and the tubes attached but I wanted my new vents to not be the limiting factor on air flow. Since as big as I can really go with the stock hoodliner is 1 1/2 inch I figure I'd ask to make sure I'm safe.
Do this.

i cut out the old top (as in the slut mod) sealed the front, added 2 2" bulkhead fittings on the tray end, put 90 fittings inside, ran 2" shopvac replacement hose (from lowes), sprayed expanding foam in top of top(under blocked retangal vents) to hold tube against inside top of hood over the motor, let them drop to floor between flywheel and tank, added liquidgraffix surf seal, added some foam pipe insulation in place of original seal, can't get enough water inside for the bilge to pump anything out.

Here is one of the best write-ups and easiest mods for the squarenose hood. I did it myself years ago and it wasn't near as difficult as it looks and the weight savings are huge.

hope this works (the photos). my idea was the hood mod should reduce water intake, minimize the water that does get in, and supply adequate air and reduce weight. about the only way water gets in is if a novice rider lays it on it's side in the water, whatever might come in goes to the floor and out the bilge, routing the pipes up the inside further restricts water from entering, 2 2inch pipes are adequate for dual carbed 62t and replacement shopvac pipe at lowes was cheap (1 piece cut in half) , with the surf seal and foam pipe insulation in the facory hood seal groove this baby stays dry. the foam is lightweight and you can cut out any extra when you foam the pipes to the inside roof of hood. after reading and looking at all the hood mods write ups I came up with this because for a guy with no fiberglassing experience, this did not require any other than blocking off existing holes (that was pretty easy to get right).

Stealing this idea 
i was looking over all of the hood mods and i couldnt tell what has actually been done. this one is simple remove old liner block off holes, make new holes let physics take care of the rest.

r6487 are you running the hood like that with no liner?
No reinforcement of the hood? It's got to be flimsy as a pancake

bulkhead fittings are expensive at your standard HW store go online and pick them up ive found most of my luck with them at aquarium shops

i got the bulkhead fittings from flexpvc for around $25 for both, and yeah I'm running it just like it appears, since I'm not doing 20ft aerials in surf and doing backflips it fine for carving and just rec riding, it's a stock 1990 sn hood, just cause the inner airflow guts are gone, don't make it worthless all the suddden. i like the lightened weight too.

Never said it was worthless, I ride a square myself. Yes i do bigger surf aerials and land wrong sometimes. Thats why i built my hood strong and reinfocred everywhere.
But one wrong landing sideways without a hood liner or reinforcement of some sort and that hood is not just going to break, it will shatter/explode with no structure underneath it.
For a test, take it off the ski and sit it on flat ground. Push down on it with your hands and you'll see the flex I'm talking about. They get real weak with the liner removed.
