98 SJ-holes in the fire wall???

[GIL]

I took the engine out to clean the hull and there are 2 1and 1/2" holes in the firewall bout 5" up-one on the left and one on the right-they are exposing foam in the hull-should they not be sealed off???

 

[CoreyLKN]

I dont think thats normal. How about some pics?:cool2:

 

[Matt_E]

Those are normal. Yamaha glued top and bottom decks together, then filled in foam through those holes. And then they put a paper sticker on it to seal it.

 

[MADMAT]

They come stock with some sticker over the hole:banghead:

Glass em' in.

 

[Shonuff]

Factory foam fill holes, newb.

Cover them up with two RCJS stickers from Zig if you want.

 

[CoreyLKN]

wow i was wrong, shows how much i know.:banghead:

Thanks guys-thats wut was there-some 'barley there' plastic stickers that came right off w/hull full of hot water and greased lightning.

Now that I know-I'll seal em off properly!

 

[waterfreak]

might want to re-foam before sealing them off
have fun!!:woot:

does the foam 'cap' keep it from getting waterlogged? (water in hull, accelerate and it goes into tray)

The foam gets waterlogged from:

The exhaust flange rivet holes
The HIN rivet holes
The rideplate threaded inserts
Water from bilge

The foam gets waterlogged from:

The exhaust flange rivet holes
The HIN rivet holes
The rideplate threaded inserts
Water from bilge

Add:
pump mounting threaded inserts
rivets around the bond line

AND the thru-hull water lines, steering cable line, scupper valve and exhaust tube screw holes

 

[Matt_E]

The potential for a waterleak into the foam exists at every bondline, fitting, and bolt insert. This includes the driveshaft PVC tube.

Yeah, I don't understand why Yamaha would not have put some kind fo a plug in these holes?

They put stickers over them????WTF:bs2:
