Screws or rivets???

Didn't run tubing, just pulled wire under the ribs. Pulled one extra pair of wires and also a stainless pull wire for future.

the 1/2" seal tight plastic flexible conduit will fit inside the rib gaps and sometimes you just need to bend the edges up slightly to get it in but its the best way. if you ever need to rerun the wires they will not follow the groove so it could be an issue if you cant pull the new wire by using the old wire such as adding something new or replacing a cut or shorted separated wire.

just something to think about before it gets sealed up.

I also used the sides to run the wires through to keep them out of the salt bath all the time to reduce corrosion concerns as well as keep maximum channels for drainage in case a few passages get clogged up under there..

Good info. Thanks

I found some aluminum channels that fit snug over the ribs, had them welded on, then screwed a 1/4" aluminum sheet on top of the channels to make the floor flat. That was almost 20 years ago and it's still going strong.

Best flotation I ever saw was a guy in Arkansas. I built him a nice motor, claimed his boat was still slower than I expected. It was a factory floor and walls in the boat. I told him to remove the floor and walls and replace the flotation. He claims that he weighed the flotation he removed, it was over 300 pounds. He replaced the flotation with clear plastic water bottles, hundreds of them. He stuffed them under the floor to prevent squeaks. Boat came out great, runs like a scalded dog now, no squeaks. I just thought that was a very innovative idea. I would never have thought of that, but if one leaks there are hundreds more to take it's place and they will NEVER soak up water.

Might be worth looking into since you are installing a new floor.
