Galway Girl Posted July 6, 2022 Share Posted July 6, 2022 This spring as we were prepping for a new road trip, I noticed the battery box door seemed to be sticking out further than normal. I thought I would adjust the latch to pull the door in a bit tighter. What I found was that the battery box had started to tip forward away from the main hull as shown the pix below. All the rivets up both sides and all across the top of the box had sheared and the box was tipped out about 1/2". I contacted Oliver Support to understand how the box was designed, mounted etc. They cleared me for travel after having me check the support strut inside the trailer (under the pantry area) . After some further consultation I was able to perform a repair. Here's a sketch of how the battery box is installed in our Hull 505 (2019 Elite II) trailer. The repair steps I took following Oliver instructions were: 1) Remove the batteries from the slide tray to get weight off the box. 2) Drill out all sheared rivets. (3/16" bit) 3) Release the 2 support bracket bolts inside the trailer under the pantry (one of which is adjustable). (This step is a pain and requires some long extensions for the ratchet wrench to make reaching nuts possible.) 4) Tip box back into position. (Check that the box base still has a slight outward tip for water drainage.) 5) Re-tighten support bolts. 6) Re-rivet all around the perimeter. 7) Clean seams and add a bead of boat life white sealant around the battery box seam. (See pix below). Repaired Box Above: Door closes with a good seal all around and the box sealed to the body. We are going to keep an eye on this as we travel this next year, and make a trip to the Oliver factory for them to inspect and repair if necessary. I'm not sure of the root cause or mechanism by which the box tipped out in the first place. One concern would be that the box is putting too much pressure on the outer hull while bouncing down the highway. I don't see any indications of cracking in the glass hull or box at this point. Hope this helps if anyone else see's an issue.
