Hello all! I have a 1974 Glastron Carlson CV-16 (about 1100lbs with motor, light fuel and just me) with a 85hp crossflow. I will eventually have a 140hp crossflow, but for now it will get the 85hp. I know this is not a performance hull, but I would like to get the most out of it as I can. Does anybody have any experience with these old boats with jackplates? If I did get one it would be a manual one. hydraulic would be nice, but too much money for this old boat. Thank you
