I have 4 electric cannon downriggers and the plugs are finally corroding out after 11 years. I ordered the new plugs for them and was curious if anyone on here knows of anyone that will swap the old plugs to the new ones I recently purchased. I'm from the Milwaukee area and havent't found a repair facility locally anywhere. Any help is greatly appreciated.

My buddy and I are new to Laker fishing and we've heard conflicting opinions on the speed we should be going to get them. I've been told the slower the better and my buddy has been told you can go your normal trolling speed 1.7-1.8mph and you'll still get the big ones sitting on the bottom. Any info or suggestions would be greatly appreciated. Thanks, tight lines! Phisherman247
