Vibrating WaterBox???

[rob1086]

Hi guys, I have GreenHulks shorty waterbox installed on my ski, and I've noticed that at idle there is a vibration coming from where it makes contact with the hull. I know some members on here have put a rubber mat of some sort under it. Did you guys get this from a store, or custom make it? Does it have to be heat resistant? Thanks in advance guys!!

I copied member "lafjax" idea for quieting some of the hull resonance that came from the GH box. We glued/covered the whole box in that rubber floor fatigue matting material. It's on sale right now at Harbor Freight for $7.99 for a pack of four. It seems to be impervious to heat as I had a high temp issue because I had accidentaly covered the pisser holes during the exhaust install, and the mat material did not suffer.

I also glued a pad of the foam to the hull under the water box. You really could do fine with that to eliminate the vibration. I like the covered box but it did not quiet the shorty very much.
