USP Marine Tuning Performance Lower Unit Plug KitGetting overheat alarms or low water pressure warnings at wide open throttle? You're not alone it's one of the most common complaints on high performance center consoles running the Mercury Marine 1. 75 HD lower unit. When you're running the lower unit at the optimal height for speed, the 8 side mounted water pickups come out of the water and start pulling air instead of coolant. The engine doesn't like that. This kit is the fix. Borrowed from race

Getting overheat alarms or low water pressure warnings at wide open throttle? You're not alone — it's one of the most common complaints on high-performance center consoles running the Mercury Marine 1.75 HD lower unit. When you're running the lower unit at the optimal height for speed, the 8 side-mounted water pickups come out of the water and start pulling air instead of coolant. The engine doesn't like that. This kit is the fix.

Borrowed from race-style setups like the Mercury Racing Sportmaster, the solution is simple: plug the side pickups and let the nose cone inlets do all the work. Clean, uninterrupted water flow at speed, no more alarms.

What's in the Kit

• 316 stainless steel plug hardware for all side water pickup inlets
• All tools required for installation

Fitment

• Mercury Marine 1.75 HD Lower Unit (found on the majority of Verado outboards)

Pro Tip: This works best when your lower unit is set at the correct height for your hull. Not sure where it should be? Call our team at (833) USP-BOAT — we'll walk you through it.
