Gear track drill bit

Just bought a pair of YakAttack gt90 gear tracks and fullbacks for the rear tankwell of my revolution 13.  I haven’t been able to find the size drill bit used for their installation.  This is my time first drilling in my new boat so I want to get everything right.
Thanks,
Joe

I made my own tracks but did follow the YakAttack dimensions fairly closely (you can read my DIY gear track project in the "drilling and cutting" section of the forum).  I seem to recall the GT90 used an 8/32 screw.  I'm going by memory so... "If that's correct", you can use either an 11/64 drill bit or a 3/16 drill bit.  The 3/16 will give you slightly more "wiggle" room to work with and is the one I would use.  You will find the thickness of our kayaks is not consistent from one hole to the next (hole spacing on your track should be 1-3/4).  Be sure to add some marine sealant between your boat and the track at each hole you drill.

You'll also get a bunch of plastic spirals when you drill the screw holes.  You might want to collect these.  You may need to do a small repair in the future and it will be nice to have a little plastic available in the right colour if you do.

 

Take the tracks in to your local hardware store and pick the drill bit   I have done that many times, make sure I get the right sizes...

Thanks for the replies, I finally finished my install.  The first track went in fine but the second one had a problem with the backing plate.  Yak Attack sent me a new one within a few days which was awesome and the second one went in quickly.  The biggest lesson I learned was drilling into a kayak isn’t that big of a deal.
Please disregard my messy garage.

Looks good.  So what size drill bit did you end up using?

I used an 11/64 drill bit.

You sure the second backing plate didn’t work because of a defect or was it that your garage was upside down?

Everyone's a first timer the first time.  Nothing to get excited about until you start thinking about hole saws and Dremel tools. 

That's a great looking install!  Nice work!

Thanks rawkfish!  One of the reasons I got gear tracks was because I saw them in some of your videos.  Even though I have drilled 28 holes in total, the versatility of the gear tracks made outfitting much easier and more universal.

Oh yeah, I forgot to say congrats on the nice, clean looking install 

The nice thing about small holes is that if you ever change your mind about what/where accessories, the holes can be easily filled with some basic plastic welding skills.
