Default Putting a Ram on a Yeti

So, story is, we're building a new boat, and I will be using a Yeti 250 Quart to be a Coffin box for the front of the boat. Problem is, the chest weighs almost 100# empty, and I'm assuming the lid is probably close to 40# or so of that weight. I was wondering, has anyone ever mounted a preassurized ram on the lid to hold it open? the same way that some in deck boxes are being held?

I'm worried that when it gets a little choppy and we go to either grab bait, or load a fish in, the boat being rocked around and causing the lid to slam back may hurt someone.

Thanks

Also, if it can be done, where do I buy one of these?

Gas Springs sound like a great idea. I'd check ebay or Amazon for best prices.

You probably need one on each side of the lid for stability then you just need to figure out where the pivot points need to be and the exact length of the piston and arm both extended and retracted plus the weight rating of the gas spring.

Down side is it could be trial and error method which may lead to numerous holes drilled into the cooler. You could build a mock up of the cooler and lid first to avoid that.

Post pics of it if you end up going this route....I may steal your idea if it works well, but I'll let you go ahead and drill the holes first...LOL

I don't think it's a terrible idea but you may have some problems. Those rotocast coolers have a fairly thin wall thickness and the polyethylene material is not the greatest for screw holding ability. PE also suffers from creep. When there is a constant load on it, the material can deform.Gas springs put a pretty big constant load on the connections due to the gas pressure,angles, and torsion involved.

You might think about installing a mounting plate to spread the load over a greater surface area than the standard mounting bracket provides. I'm thinking 1/8" aluminum or stainless, something 2-3" square. You could put 8 screws around the perimeter and maybe even use some G-Flex epoxy to bed the plate (I've heard it sticks to PE fairly well if flame treated). You could then tap the plate to install the mounting bracket.

Another idea would be to core out the foam where the mounting bracket will be placed and fill with epoxy. You could then drill and tap into the epoxy.

dont waste your time we use the 240 engel on the front of my sea vee and the lid opens past vertical and has never closed on anyone. and agree with the issues of drilling into a roto molded plastic lid.

I think this a great idea, or maybe the springs I have on my live well. When open they hold their shape and to close them you bend them some and they fold right up.

Did you ever do anything? Personally a 100# cooler sounds like an issue to me...

Have a custom coffin box made. Its made of divinylcell or similar and would weigh a fraction of a Yeti. Plus it would look better.

And you still could put a lid support on it....

^ x2 on this. Wait until you get the cooler and see if you really need a ram on it. I have a big one (actually a RTIC copy), and the lid stays open just fine on its own - and I doubt the lid weights 40#, maybe 15/20 max.
