Marine Fuse Block Replacement
A small leak that only reared its ugly head in very windy rain last season created a bad situation for the wiring and fuse block inside of the hardtop. The power cable to my Furuno radar was damaged as and the fuse block suffered some corrosion as well. I removed the fuse block and replaced it with a new one.
Here is the old one…
This is the new one…
I also re-terminated all of the wires with new ends. The only end I could not replace was the Furuno power cable due to the proprietary connector. I had to order it. My concern now is to figure out how the water is entering the hardtop. It sure isn’t obvious because all of the seals on the top look good. I resealed them all anyway with the hope that I’d get lucky. Time will tell if the problem still exists. This week should be a very good test seeing is how it has been raining with 30mph gusts all week. Boat maintenance and repair are never ending. How does that saying go “a boat is hole in the water into which much money is thrown”.

I saw this post on a boating forum I don’t know if it helps.
Your hard top could be letting water in from one or several places around the bolt heads that hold many diffrent things on the roof top. This is what this guy did he said that he not only stopped the leak but it looks good too.
Since you don’t know which bolt is letting water in start on the front-end and work your way to the back.
You will need white or clear silicone, painters blue tape, alcohol to clean over the heads of the bolts/fiberglass and two metal washers one larger than the ohter.
Determine the diameter you want to make your plugs with the sealer and find a metal washer that size then another washer the size of the bolt-heads on your roof.
If you can find one metal washer that has those two size diameters then all you need to do is to trace the metal washer on to the blue tape and place these round blue tape washer over the bolts (do this over some other surface not on the roof) on top of your roof and seal over the center open hole and then just remove the round blue tape and you end-up with a nice round plug over your nut heads looking like it was made at the factory.
You may want to do them all so it looks more the part.
Most of the work is making the round forms out of blue tape.
I hope this makes sense. I had to read it a few times. Good Luck! I don’t know if this is the problem you were having but it sounded like it might work.
