View Full Version : Finbox in iSonic
9th July 2011, 03:48 AM
While increasing the diameter of the fin screw holes in my 2010 isonic 101, I somehow managed to make a small gouge/chip in the side of the box. Now, I know that I was probably stupid to mess with the finbox in the first place, but can somebody tell me if the board can somehow take in water there?
Or is the tuttle finbox cassette made out of not water absorbing material anyway? I guess I can fill in the gouge, but if it's purely cosmetic then I don't want to risk compounding my stupidity.... This is the most expensive board I've owned so I'm being paranoid around it.

OK, is the "small gouge/chip in the top of the finbox (up where the screw holes go thru to the deck,
or is it near the bottom surface of your board.
Either way, there is quite a bit of material (approx. 1/2" (12-13 mm) all around the fin cavity, and the
finbox is moulded out of a reinforced epoxy/plastic material that is completely waterproof.
I think you will be OK.
Any explanation as to why you needed to enlarge the fin screw holes?
Hope this helps,

Thanks Roger, I will sleep better. The gouge is near the bottom of the board - not where the fin bolts attach.
What happened is that for mysterious reasons, one of my tuttle fins have the fin screw positions a bit forward than standard. This wasn't a problem on my older board that did not have the recessed deck. The isonic is quite precise where it wants the fin screws. So, I am elongating a bit the holes for the fin screws. I don't think this will compromise anything - I hope?
It's a decent fin, and I want to try it with my new board.
thanks for the advice - it's very appreciated!

Ahhh.... fin screw alignment issue.
I have a "rat tail" round hand file for that.
If you work the holes from the top there is very little possibility of damage.
