has anyone tried adding a fitting to inlet side of xmetal waterbox and adding water there to reduce sound without affecting the water at the pipe stinger?
If you are going to add water anywhere it needs to be at the outgoing side of the box. Only my opinion, but the best way to make one quieter is to replace it with an OEM RN waterbox. They make fantastic power(none have been proven better) and are relatively quiet. The weight difference is only a couple of pounds and as long as you're using a flow control valve/restrictor at the stinger there's no difference in how much water is in the box. The real advantage is you don't get thrown off the lake or further damage public opinin of jetskis.

I know it seems like a crazy thought but I did this and it works GREAT. Get rid of the Xmetal they are nothing but noise makers!
i was kicked off the lake last year because my ski was to loud with the xmeatl water box, lol
