The Margay does pop up when released on the 3″ frame when it flexes, that is normal. This should not be as noticeable when launching as the buoyancy of water on the transom floats the rear and reduces frame flex. The bow eye is probably loose from outside only and the nuts should have red permanent LokTite on them. If they do not have red LokTite then apply some and tighten them. If you have to access that area the front trolling motor panel is your only area, port side of trolling motor pedal. The other option is a screw in access port to cover a hole, which we do to mount a RAM on some applications. Hope you enjoy the rig and it serves you well. BCB
