G3 1860 Upgrades with Battery Relocation and Hydroturf

So after having my boat for a bit, I decide it needed some much needed upgrades.  First was upgrading the 12v 40lb thrust trolling motor, second was installing some type of 'Hydroturf' flooring. Also when I was working under the front deck, I figured I'd put in 3 rod tubes to allow my fly rods to be assembled while in the side rod holders.  

You can see the general layout of my boat here:


So I tackled the battery issue first.  I bought a 70lb 24v hand control trolling motor, and the next issue to tackle was where to put the extra battery.  In my particular model, the 20 gal gas tank is in the back, along with the deep cycle, and starting battery.  Adding a third battery I felt would simply be too much weight in a back of the boat.  It already sat a bit low in the back with 1 person and a full tank of gas.  My mission was to figure out how to put the 2 deep cycles up under the front deck.

I took out the storage bins to see what was doing underneath.  You can see the "firewall" in front of the boxes in the picture below.  That whole area forward is solid foam for emergency flotation.  There is a channel that runs down the middle that just so happens to be about as wide as a battery conveniently.  Since 2 batteries would not fit in the open area if I wanted to keep the storage bins in use, I had to cut that "firewall" to make room.



I then mounted a 1/2" piece of painted plywood with rubber shower pan material under the plywood (to reduce vibration, and create something of rubber washer/gasket effect) to mount the battery trays to.  It fits snug as a bug.  Cutting the "firewall" was a major pain just because of the angles I had to hold the jig-saw.  I broke off a few blades in the process.  I put some rubber trim in the cutout area because it is super sharp, and I couldn't really reach in there well enough to smooth it off sufficiently.



I checked the fit before bolting everything in permanently.



After installing the batteries and wiring them in series to be 24v, I snapped them in.All I had to do was wire up the on-board charger and charging port.




Before bolting the storage bins back in, I installed the rod tubs on the side by using a hole saw the diameter of the 1 ½” PVC pipe.  I flared the end using the heat gun I had used in all the wiring to heat the end, and then squished the PVC over the neck of a beer bottle.  It worked like a charm.  I covered the pipes with rubber electrical grommets purchased at www.customgheenoe.com



I put the boat on the water the next weekend and it sat almost dead flat in the water.  I certainly allowed me to draft a couple inches less.  On top of that, it got on plane almost twice as fast as before, and will get on plane at lower speeds.  The only downside is I can’t get the nose up as much with the extra weight up front, and I lost between 1 and 2 mph off my top speed.  The positives drastically outweigh the one negative.

Here's the video summarizing step by step:


Next was upgrading the flooring.  I looked into Hydro Turf, and discovered that there is an EVA foam you can buy for about $20 for a 4’x8’ sheet that a lot of folks were using instead.  The brand is ‘Best Step’.  It feels similar to a yoga mat, but much sturdier, all while weighing next to nothing.  It’s the exact same material as Hydro Turf.  It's made of the same EVA high density foam as Hydro Turf and feels almost identical. 

Here's the link to where I bought it:
Lot's of other folks get it from Sears.  In fact you will find posts online referring to it as “Sears Hydro Turf”.

It took 4 rolls to do an 1860 boat (well 5 since I trashed one roll which I’ll explain how to avoid doing so).  Can't rave enough about the stuff, and every single review I read from folks that put it on their boat absolutely love it.  The sound insulation benefits alone make it worth doing on top of comfort on your feet, and not burning my skin in the hot weather when barefoot or sitting on the deck.  I have have been modestly rough with it, and it shows no signs of wear.  It cleans up super easy too.  Plus each roll weighs next to nothing.  Putting it in my boat might have added 10-15 lbs including adhesive.  It wasn’t quite as easy to install as I hoped since I did it without a second set of hands, but it was by no means difficult.  An extra person to help you line it up lay it down when you've applied adhesive would be a big help.

Doing this on a warm day is important as it relaxes the material more, and it will lay flat for you.  You will use Weldwood adhesive applied with a foam roller.  For 4 rolls, adhesive, and the cheap roller, the project cost about $100.

I measured and laid out the floor after cutting it out to make sure it lined up.


Here's after I put the glue down and didn't line it up right thinking I could adjust it a little before the glue stuck...I was wrong.  When using Weldwood contact cement, you put it on the boat, and the foam flooring, and let it dry for 5-10 mins before laying down the floor.  Note that AS SOON as it touches each other, it's stuck for good (unless you want to tear it off in tiny pieces like I had to).


Here it is done.  Sorry for no detailed install pics:
