I thought I would share with you all my tackle mod for my 2018 921. Phoenix changed the compartment, no more rods and no more angled insets. It’s all flat now expect for a small lip on the side shelves. I didn’t like how my original take mod I made years ago fit in 2018. It left a small gap under the king starboard where it tied into the the sides. So I made two boards (walls) that run the length of the compartment. When I made the original tackle mod years ago, I designed it to keep bags of soft plastic from falling onto my boxes and to have a shelf across to store spools of fishing line without them bouncing all over the place. The problem I ran into after making the shelf on the old mod was I couldn’t access the most forward boxes without taking some of the other boxes out first. The shelf covered the boxes up. So I got to thinking.... how do I fix it? After a few minutes it hit me. I have a few extra black trays Phoenix puts in the battery compartment. Wonder if one of the black trays will fit between the two boards (walls) I added. So I go get one of them, drop it in and it fits perfectly. SWEET! Then comes my next issue. I know the black tray is going to slide back and forth, and that’s what I want. The sliding tray lets me access the forward boxes. However I didn’t want the black tray to be right in front of the compartment every time I opened the lid after running down the lake. So I measured the black tray lip and cut a notch on the topsides of the boards (walls). You maybe able to see it in the pics. This worked great when I slid the black tray to the back. It fell right into place and made it all flush. Later I got to thinking more about the tray. Knowing how rough the water can get on Guntersville, I knew the black tray would eventually bounce out of the notches. I then decide to put a strong magnet on the backside of the tray and the bulkhead to insure the tray wouldn't move until I wanted it to. Once I installed the magnet the tray actually snapped into place when slid to the back. I got the magnet off amazon which is a pull of 77lbs. I was concerned the magnet maybe to strong, but it worked perfectly. Tackle Mod 2018 is much simpler and does the same thing as the old.
