About Marine 316
We build it, we sell it, and we install it.
Marine 316 is the online store of Engineering Performance Innovations, LLC — a Florida company that designs and manufactures marine products, and runs the shops that put them on boats and cars.

Who we are
One company, from the workbench to the water
Marine 316 is operated by Engineering Performance Innovations, LLC, founded in Florida in 2023.
We started the way a lot of good shops start: doing the work ourselves, getting frustrated with the tools and materials available, and deciding to make better ones. That first frustration turned into a product line, the product line turned into a store, and the store turned into Marine 316.
Today the company does three things that feed each other. We manufacture a good share of the products sold here under our own M316 brand. We sell those products alongside carefully chosen gear from brands we actually use. And we install them ourselves, in our own shops, on customers' boats and vehicles.
That last part is what keeps the other two honest. Every tool and every film we sell has already been tested by our own installers, on real jobs, with a customer waiting.
What we do
Three sides of the same business
01
We manufacture
Many of the products in this store are designed and produced by Engineering Performance Innovations, LLC — including our M316 films, blades and application tools. When something we need doesn't exist, or doesn't hold up, we build it.
02
We sell
Marine films, window film application tools, PWC and boat accessories, content creation gear and more. We stock what our own installers reach for, from brands like Tri-Edge, SolarGard, Insta360, RAM Mounts and NT Cutters.
03
We install
Our installation shops apply our products to boats, personal watercraft and vehicles: marine window film, protective films, wraps and accessory fitting — booked by appointment and done in-house by our own crew.
Our shops
Book it, drop it off, get it back better
If you would rather have it done than do it yourself, our installation shops handle the whole job — on the water or on the road.
Every job runs through the same simple track, whether it is a full marine film application on a center console or an accessory install on a truck. You get a written estimate before anything starts, a scheduled appointment, and updates as the work moves — so nobody is left wondering where their boat is.
Step 1
Estimate
Tell us the boat or vehicle and what you want done. We put the scope, the materials and the price in writing before we start.
Step 2
Appointment
We schedule the drop-off and confirm it with you, so your boat or vehicle is only with us for as long as the job needs.
Step 3
In the shop
Our installers do the work and log it against your job. If something changes, you hear about it from us before it happens — not after.
Step 4
Ready for pickup
We let you know the moment it is done, send the invoice, and you can settle it before you arrive.
We keep a service history for every boat and vehicle that comes through the shop — what was installed, which materials, and when — so a warranty question or a repeat job years later starts with a record instead of a guess.

Browse the store, or bring us your boat. Either way you are dealing with the same people who made the product.
