Hello,
I recently purchased a troller and am now taking care of some of the little things. This includes re-mounting the gurdies and the board they were mounted to had split. I can't seem to find any plastic threaded rod to re-mount the gurdies locally. Anyone know any places online that will sell small quantities? Seems most places online that have it aren't retailers so won't bother with a small order.
Thanks,
Stephen

Tideland Tackle in Hoonah had some. 907 945 3463 ask for Dave. He loves to sell fishing gear.
Anyone know how strong that stuff is?

Thanks for pointing me in the right direction. I was wondering about the strength of plastic threads. I've been asking around and looking around and it seems all the ol' timers swear by the stuff.
My gurdies are mounted on a wood board which is mounted to the boat on thick plastic blocks. The gurdies are then mounted to the wood board on plastic fairleads using the plastic threaded rod. The gurdies are then tied into the bonding for the boat.
Would using stainless bolts with plastic washers to bolt the gurdies to the wood board be ok or would it create problems?

Maybe you just made a typo but I think you want to "isolate" your gurdies from the bonding system so your wires create a positive field different from the boat. Even isolate your hydraulic hose if you are power trolling....you want your gurdies to be on their own and not connected to the boats bonding system. Thats just my opinion but I know others can tell you the same thing.
Stainless steel?
Most people will tell you to keep your metals similar as far as things on your boat. Similar meaning the noble scale similar. I would think that a silicone bronze would be closer in similarity over stainless steel if you are talking about a wood boat.

Thanks for pointing out my error Jim. You are correct, the gurdies are tied to a zinc, not the bonding system.
I've learned the hard way over the years about dissimilar metals. In this case, I was thinking by using plastic washers I can eliminate contact between the bolt head and the gurdie. Then by rigging a rubber sleeve on the bolt shank I can eliminate contact between the bolt shank and the gurdie. The only reason I'm considering this is because I can't find any plastic rod. However, I did find a place that has silicon bronze so will probably just go with those.

Murray Pacific in Sitka, 907-747-3171, has plastic threaded bolts just for this purpose. You do not want your gurdies tied into anything except your black box. You want them isolated from all your boat's metal and zincs. You want all your zincs tied together with your bonding strap(s).
Good luck!

Well, I was able to get a piece of 3/8" threaded rod from the Murray Pacific in Ketchican, the woman I spoke to at the Sitka location said they didn't have anything. I tried Tideland as well and no luck. Any places down in Seattle I should contact?
What other materials are you guys using for mounting bolts? I'll try and get a picture tonight of how mine are mounted.

You can also use rubber washers and get some graphite bushings and assemble with a metal bolt. if properly sized you will be completely isolated.

Hey, I suggest you take an ohm meter to those graphite bushings. When I read your suggestion, an alarm went off in my head saying "graphite conducts". I asked my overeducated daughter, and she said "no". But I checked wikipedia and it left the door open. So I just took an ohm meter to a pencil refill, and it read 1.5 ohms. Maybe it is not true graphite, or something, but why not take an ohm meter to your graphite to remove all doubt?
