Waaay back, I had a pair of cannons that would burn up the brushes every few years due to the tiny wires and plug system they came with. I havent checked them out in more than a decade but if they still come with the 14 gauge wiring and mickey mouse plugs I'd beef that up first.

Most Montauks are a tough application for downriggers. Don't skimp on the mounts! I recently helped my friend bastardize and improve some old railmounts for his montauk. You might want to have a mounting system or another rail post fabricated to get these exactly where you want them!
