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 😄

Fitment

  • Mercury V10 350
  • Mercury V10 400 (mainline)
  • Mercury V10 400R
  • Mercury V10 425

Great sunscreen!
Size: 6.7 Fl Oz (Pack of 1)
We have used this sunscreen lotion on multiple beach vacations, and most recently on our cruise. The quality, coverage and protection are great. The lotion glides on smoothly and is not sticky. It has a light fresh scent that did not irritate the members of the family with sensitive skin. This is one of our favorite lotions to use, and we keep repurchasing it. The price point is great as well.

It works
Size: 6.7 Fl Oz (Pack of 1)
Well this product works. At first I thought maybe the Caribbean sun wasn’t as bad as people said since I was in the sun for 4 days wearing this sunscreen and hardly had tan lines, then I tested my theory for 1 day with another brand and got a sunburn. I took star off (would really only do a half if it allowed) for when you go in the water or if you sweat there is a bit of white residue that it leaves. But for sun purposes, if you want protection, I highly recommend.
