This t top is suppose to tilt but by being made in China there quality control is not like ours. If you took the knobs loose and tilted it you would not be able to get it back together without a lot of tools and help. I don't plan on tilting it as it is going to spend it's time tied to my dock.
Very nice looking rig! Can’t beat the open floor plan and room a pontoon provides. I have that same Johnsuki 140 HP OB. Been a great motor for me! Starting to see a lot more CC pontoons. Excellent fishing platforms, especially with how well todays TMs move them along and hold them in place. Best of luck with it.
