down rigger

I am selling two 1101 electric downriggers that came with my new boat (already have 2). Tested today and all work well. Comes with swivel bases. *old style plug it can be swapped easy enough. $700 for the pair Located in Victoria

Call it luck but I haven’t lost a cannon ball in 3 years... Net result is I have several 15 lb balls all banged up, some with some corrosion. I can’t see these balls (most with fins) tracking through the water smoothly. How about others, do you replace your cannon balls when they get to this state?

Hoping someone has an old Cannon downrigger that they have for parts as my circuit board is shot on my Mag10 HS downrigger and I've just been notified that Cannon is no longer manufacturing this part. Looking for part#3394002 or any suggestions how I can fix it. I've checked Amazon and Ebay...
