what's the hole for?

[tilleryrat]

anybody know the purpose of the approx. 1" hole near where the exhaust tube goes through the back of engine compartment on a 01 sj? It has a plain white sticker over it.

i believe there is one on both sides of the intermediate housing... it's what the factory uses to pour the foam behind the bulkhead.

does anybody glass them, or leave them open?

i glassed over mine. I've had the tape come off which can allow water to soak into the foam.

Yes, folks glass them over, to help keep their foam dry. Those cheesy sticker they put over the holes are worthless

 

[tilleryrat]

cool thanks!

If your ski takes in water from the back and you have no drain would the hole not allow the water to enter engine room and then can be bilged out... ??

the foam wont really absorb water there, the skin on the foam seals good.
you have MANY other holes in the bulkhead you should be worrying about.
exhaust tube, cooling lines, and steering cable tube all need to be resealed

no water doest flow through the foam, once its wet, it will always be wet.

well I noticed mine draining a bunch of water out when picked the tail of the ski up. Should I glass it or will this just trap water in?

I would say its too late to seal off at this point, maybe refoam on the off seaso. I know I went crazy with the 5200 around the bulkhead and through fittings after I found all the leaks with low pressure compressed air.

I've got two 'test plugs' from Lowe's in mine - you have to shave the end down a little bit but it works good.
