Mercury – Analog Water Pressure Fitting Kit | Engine Port Hardware | 32-8M0063663

Overview
This kit gives you the engine-side fittings you need to hook an analog water-pressure gauge to a Mercury F150 EFI FourStroke. It taps the engine’s pressure port cleanly and sends a steady signal up to the gauge. Out on the water, it helps the gauge read smoothly so you can keep an eye on cooling flow without guessing. It’s a simple, bolt-on kit made specifically for the F150 EFI.

Key Features
    • Engine-Side Fittings – Provides the parts needed to connect tubing to the pressure port.
    • Steady Pressure Feed – Helps the gauge track water flow accurately.
    • OEM Thread Fit – Matches the F150 EFI pressure port correctly.
    • Marine-Ready Hardware – Built to hold up to heat, vibration, and spray.
    • Gauge-Compatible – Works with standard Mercury water-pressure tubing.

Engine & Boat Compatibility
    • F150 EFI FourStroke
    • Analog water-pressure gauge systems
    • Dash-mounted pressure gauges
    • Mechanical rigging setups

Performance & Practical Benefits
With this kit in place, the gauge gets a clean pressure signal right from the block. That helps you spot low flow early—things like weeds on the intakes, shallow-water strain, or a pump that’s starting to weaken. Installation is straightforward, and once it’s tightened down, the gauge usually settles into a smooth, reliable reading.

Why Buy OEM
OEM fittings seal properly, thread smoothly, and stay tight under vibration. They’re made for the exact port and don’t require forcing or shimming. Most boaters stick with OEM for cooling-system parts because one bad seal can throw the gauge off.

FAQ
1. How do I know if I need this kit?
If you’re adding an analog water-pressure gauge to an F150 EFI, this is the correct engine-side kit.

2. Does it include tubing?
No—this kit provides the fittings; tubing is sold separately.

3. Do I need thread sealant?
A small amount of marine-safe sealant helps, following Mercury guidance.

4. Is installation difficult?
It’s usually simple—locate the port, install the fitting, and hook up the tubing.

5. What if the gauge reads low after install?
Check for leaks, loose fittings, or debris in the pickup or engine port.
