Yup 2 new sprockets are in order. Both are missing some teeth. This one is fubar. It only has 4 teeth left (all on one side).
A couple more questions (if you'd be kind enough):
1) Any tips on getting the masts out of the sprocket? A little heat on the mast? WD40? Don't want to trash those. Thinking maybe they were loc-tited at some point. 2) Where to buy? Looks like Austin Kayak has some of the parts but maybe not all. Better off buying direct from Hobie? Is that possible? 3) Shaft is a little worn--might replace while I have it apart. Cable ends have a bit of rust but not terrible, chains seem fine, Probably replace the idler pully as it looks kind of "tired" and is the same material as the sprockets. 4) Am I doing something wrong to break these teeth? I read that too long a stroke can cause the fins to hit the yak. I'm tallish and had the pedals set all the way out (position 7). Maybe I should back it off a step?
Thanks again. Bummer, I'd hoped to go out tomorrow. Might be rainy for a few days though. May be a blessing in my case!!!
INSAYN:
You could apply head to the masts, and let it soak down to the threads, but since you are already replacing those parts, a little melted plastic won't hurt.
WD40 is useless in this situation. It is not the best for penetrating oils available. If it's Lock-Tite, no oil is going to help. Acetone soaking the threads if the heat doesn't budge it.

Hey, Andy, I'm no help with the rebuild, but just a note: I found that my Revo 13 with the V2 drive and turbo fins was faster in the water with a short stroke on the pedals (and less tiring to me, too). I started out pedaling all the way, then after watching some online videos where I could see the pedals, I noticed that most folks were using maybe half of the distance the pedals could travel. That was about right for me, and I changed how I pedaled. YMMV.

Thanks. I'll have to give that a try. I was kind of doing that yesterday as it seemed to work better. Probably because I was missing all the teeth on one side of one of the sprockets!

Hobie seems to require $5 shipping on all of their orders, so I tend to just order everything once and spend that $5 once.

What's up with Hobie's website? You can't click on any of the items to order and I don't see any kind of shopping cart. Do I need to call them? What is this 1950? Do I need to fill out an order form and mail it in?
Looks like there's stuff that's discontinued too. I don't really want to order a sprocket kit with the masts (they only list that with standard fin masts and I have turbo) I guess that means I have to pay for masts I'll never use and already have spares of? I read that you can use GT sprockets and masts but they cost more and I wonder if they're that much better.
There are also part number discrepancies between their parts diagram and their website.
Grrr...Just a little rant, I'll work it out.
Thanks again for all your advice though, much obliged.
