Securing portable fuel tank to aluminum floor

Pic's deceiving.

Thanks.

FWIW, I once dove the shale with waves breaking over the bow while on the hook. Came back to boat with more than a foot of water in the boat at the transom. Battery was completely submerged. Motor started right up. Go figure.

I completely submerged the back of my boat while beached on Angel Island. Freighter threw a massive wave into my boat. That is one of the reasons I wanted a bilge pump, and an elephant trunk. Anyhow same thing as you the battery was completely submerged. The boat turned over no problem. What happened though is the battery terminal on the positive side corroded away the bolt, and required all new cable ends.

On my thundercat i have 2 patches glued to the floor with a fabric loop attached. Theres then a ratchet strap the goes around the tank & through the loops securing it to the floor. & if your worried about too much weight at the back how about a small tiller extension so you can sit further foward in the boat?

Definitely an interesting thread. I haven't totally submerged my battery so far, but I always wondered what would happen. I guess they don't short out catastrophically, but does it kill the outboard if it's running? Crossing bars I often pull my battery and strap it down on top of the console bench. Haven't gotten over run by set waves yet, but it just seems like a matter of time. I like the idea that a boat full of water won't necessarily mean bust out the paddles!

Doubt it. No reason it should. I mean if it starts with the battery submerged, well...

We had the same thing happen, the battery was under water for about 15 minutes while running and we couldn't do anything about it. Changed the battery cable clamp connector and still have the standard wet cell battery a year later starting perfectly.
