USP Marine Tuning MAX+ Forced Air Duct For Mercury V10 Engine FamilyThe USP Marine MAX+ Forced Air Duct is engineered specifically for Mercury V10 engines to solve a well known power robbing problem: the "station wagon effect."

The USP Marine MAX+ Forced Air Duct is engineered specifically for Mercury V10 engines to solve a well-known power-robbing problem: the "station wagon effect." This happens when exhaust fumes get pulled back into the engine intake through the rear of the cowling at speed — causing power loss, reduced top-end performance, and increased fuel consumption. The MAX+ duct channels clean, high-pressure ram air from the top of the cowling directly into the intake, pushing exhaust gases away where they belong.

Designed with the Mercury 400R in mind — the performance leader of the V10 family — this duct maximizes airflow to match the engine's demands. The 400 mainline models benefit equally from the upgrade.

Built in the USA. Built from Fiberglass.

The USP Marine MAX+ Forced Air Duct is manufactured right here in the USA using premium fiberglass construction — the same material trusted in motorsports and offshore racing applications for its superior strength-to-weight ratio, rigidity, and long-term durability in harsh marine environments. Advanced 3D scanning technology ensures a precise, Lego-tight fit to the factory V10 cowling every time. It's surface-prepped with an adhesion primer so it's ready for your color of choice straight out of the box.

Performance Numbers

  • 50%+ increase in ram air intake over the factory duct
  • Significantly reduced intake air temperatures at WOT
  • Retains 2–3 MPH in top-end speed — even more on boats running 100+ MPH
  • Blocks exhaust fumes from re-entering the intake (station wagon effect)

Highlights

  • Fiberglass construction — USA manufactured
  • Race-inspired F1 profile design that follows OE cowling lines
  • Precision 3D-scanned fitment — drops in like a factory part
  • Surface prepped with adhesion primer — ready to paint your color
  • Includes 3M 4000 marine adhesive for a secure, permanent install
  • Larger gains on 100+ MPH boats
  • Air being forced into the engine is Non-consensual 😄

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?: I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them. The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.

Silicone socks
Size: M (up to size 9)-Beige
The socks are sized large. The quality of the silicone is good. But they slide around on your feet if you try to walk, making them difficult to use and a bit uncomfortable. Unless you are able to sit for long periods of time the likely will not work well. Recommend looking for a better value.
