X4XZ Fuel Primer Choke Solenoid for OMC/Johnson/Evinrude 5007356 — Corrosion‑Resistant Direct Replacement, Fits 9.9–300HP

X4XZ 5007356 Fuel Primer Choke Solenoid is a direct-replacement primer choke solenoid for select OMC, Johnson and Evinrude outboards designed to deliver fuel on the first pull for faster, more reliable starts.

This compact solenoid restores the fuel-priming function on compatible outboard engines so you get consistent starting performance without repeated pulls or frustrating fuel starvation at startup. Engineered to match original equipment specifications and fitment numbers like 5007356, 5828665 and 397909, the unit is built from corrosion-resistant materials to withstand marine environments and frequent use.

Which engines and part numbers will this solenoid fit?

The X4XZ 5007356 primer choke is made to replace several OEM part numbers and fit a range of OMC, Johnson and Evinrude outboards from the 1980s through the early 2000s. Check your engine model and year before ordering to confirm compatibility.

• Fits 1980–2005 Johnson & Evinrude 9.9–300 HP models
• Compatible with 1991–1993 OMC 90–115 HP Quiet Rider units
• Also suits 1982–1990 OMC engines from 1.6L to 4.0L
• Direct-replacement for part numbers: 5007356, 437233, 437238, 43762, 434326, 397909, 582865

How does this primer choke improve cold or difficult starts?

The solenoid supplies an immediate pulse of fuel to the carburetor or fuel system when you pull the choke, reducing the number of pulls needed and lowering engine strain during startup. It helps prevent lean conditions that can make cold-starting unreliable.

• Delivers quick, measured fuel flow on choke activation
• Reduces repeated priming attempts and starter wear
• Stabilizes initial combustion for smoother idle after start

What are the construction and durability features?

Designed for marine use, the X4XZ 5828665 solenoid uses corrosion-resistant components and robust internal parts to resist salt, vibration and changing temperatures. The unit is made to meet or exceed OEM durability expectations for long-term service life.

• Corrosion-resistant housing for marine environments
• Heavy-duty internal components to withstand repeated cycles
• Quality control to ensure consistent fit and electrical response

How easy is installation and what after-sales support is available?

Installation is straightforward for anyone comfortable with basic outboard maintenance—mount the unit in the original location and connect the existing wiring and throttle/choke linkages. X4XZ supports the product with customer service and a one-year limited service period for peace of mind.

• Designed as a direct replacement to match mounting and wiring
• Basic hand tools typically required; no major modifications
• 24-hour customer service and 1-year product support available

Who is this for: Boat owners and mechanics who maintain older OMC, Johnson and Evinrude outboards and need a reliable, OEM-compatible primer choke solenoid to restore consistent starting performance. If your engine shows difficulty priming, requires multiple choke pulls, or you want a durable replacement built for marine conditions, the X4XZ 5007356 is a practical upgrade that aims to reproduce original fit, function and longevity.
