So, for my '03 Cougar I have issues with the 6" jackplate and hydraulic steering lines hitting the top of the transom when motor tilted up. So, I am thinking real hard at installing a hydraulic jackplate. Basscat says that I shouldn't go thicker than 6" but all they sell on the website is 8" plates. That and since they use a 6 hole plate bolted to transom I am limited to purchasing from them. I'm sure I can get by with 8" but will it cancel BC hull warranty?
