EMP Wire Lead Ignition Shift Interrupt #500492
$23.23
$27.73
EMP 500492 Wiring Harness
Wire Lead, Ignition Shift Interrupt
The EMP 500492 is an ignition shift interrupt wire lead for Marine Power engines. The shift interrupt system is a safety circuit that prevents the engine from starting or limits RPM while the drive unit is in gear. The wire lead is the electrical connection that carries the interrupt signal between the ignition switch and the shift interrupt switch. When this lead fails or develops a fault, the result is typically a no-start condition or an engine that won't rev past idle, even when the drive is in neutral.
If you're chasing an intermittent no-start or a stuck rev limiter on a Marine Power engine and the ignition switch and neutral safety switch have already checked out, the shift interrupt wire lead is a logical next step in the diagnostic process. It's a low-cost part that's easy to overlook but can cause symptoms that look like a much bigger problem.
This is a direct replacement for Marine Power part 500492. Confirm your engine uses the Marine Power shift interrupt system before ordering, as wiring configurations vary across engine platforms and model years.
Function: Ignition shift interrupt circuit wire lead
Application: Marine Power engines with shift interrupt ignition system
Common symptom of failure: No-start condition or RPM limited to idle in neutral

EMP Wire Lead for Hobbs Switch #500101
$24.16
$28.84
EMP 500101 Wiring Harness
Wire Lead, Hobbs Switch
The EMP 500101 is a wire lead that plugs directly into a Hobbs switch on Marine Power engines. A Hobbs switch is a pressure-activated switch that closes when oil pressure reaches a set threshold, commonly used to trigger an engine hour meter or an oil pressure warning circuit. This wire lead is the electrical connection between the Hobbs switch and the engine harness or instrument circuit it feeds.
If your hour meter has stopped logging time, or an oil pressure warning circuit isn't responding correctly, a failed or disconnected Hobbs switch wire lead is a straightforward place to start the diagnosis. The lead plugs directly into the Hobbs switch connector, making installation and replacement quick.
This lead is a direct replacement for Marine Power part 500101 and is designed for use with the Hobbs switch part number 457007. If you're replacing the switch and lead together, source both part numbers for a complete repair.
Function: Wire lead connecting Hobbs switch to engine harness or instrument circuit
Application: Marine Power engines with Hobbs switch hour meter or oil pressure warning circuits
Plugs directly into Hobbs switch connector

EMP Wire Lead coil to Harness Pigtail #500442

$18.85
EMP 500442 Wiring Harness
Wire Lead, Coil to Harness Pigtail, Delco EST Ignition
The EMP 500442 is a coil-to-harness pigtail wire lead that connects a Delco EST ignition coil to the original engine wiring harness. It's the adapter that bridges the gap between the new coil and the existing harness when upgrading to the Delco Voyager ignition system on a Marine Power engine.
Without this pigtail, the Delco EST coil connector and the original harness connector don't mate directly. This lead solves that cleanly without splicing or modifying the original harness, which keeps the installation reversible and the wiring tidy. If you're in the middle of a Delco Voyager upgrade and the coil won't plug into the harness, this is the part you're missing.
This is a direct replacement for Marine Power part 500442. It's also the correct pigtail to have on hand any time a Delco EST coil is being replaced on an engine that uses the original Marine Power harness configuration.
Function: Connects Delco EST ignition coil to original Marine Power engine harness
Common use: Delco Voyager ignition system upgrades
No harness splicing or modification required

$53.99
$64.78
EMP 500428 Wiring Harness
Wire Lead, Coil to Distributor, 3.0L-8.2L Carbureted Engines
The EMP 500428 is a coil-to-distributor wire lead for carbureted Marine Power engines ranging from 3.0L to 8.2L. This lead carries the high-voltage signal from the ignition coil to the distributor, which then routes it to the correct spark plug at the correct time. It's a fundamental part of the ignition circuit on any distributor-based, carbureted marine engine.
A failing coil-to-distributor lead typically shows up as a misfire, hard start, or no-spark condition. Because the lead carries high voltage, even a small crack or pinhole in the insulation can cause arcing and intermittent ignition faults that are frustrating to diagnose. If the coil and distributor have both checked out and you're still chasing a spark issue, the lead between them is worth a close look.
This lead covers the full range of carbureted Marine Power small block and big block applications from 3.0L/181ci through 8.2L/502ci. It is specific to carbureted engines with a distributor-based ignition system and is not applicable to electronic fuel injection or distributorless ignition setups.
Function: Carries high-voltage ignition signal from coil to distributor
Fits: Carbureted Marine Power engines, 3.0L to 8.2L
Ignition type: Distributor-based systems only (not for EFI or distributorless ignition)
Common symptoms of failure: Misfire, hard start, intermittent no-spark condition

EMP Connector Plug for 95a Alternator #471019
$19.98
$23.85
EMP 471019 Wiring Harness
Connector Plug, 95 Amp Alternator
The EMP 471019 is the wiring harness connector plug for the 95-amp alternator used on Marine Power engines. If the connector on your alternator harness is melted, corroded, or physically damaged, replacing the plug is a clean fix that avoids splicing into the harness or replacing the entire alternator assembly. It's the right repair when the alternator itself is still good but the connection isn't.
This plug is specific to the 95-amp alternator application. Alternator connector plugs vary by alternator amperage rating and body style, so confirm your alternator is the 95-amp version before ordering. A mismatched connector won't seat correctly and can cause intermittent charging faults that are frustrating to track down.
This is a direct replacement for Marine Power part 471019.
Function: Wiring harness connector plug for 95-amp alternator
Application: Marine Power engines with 95-amp alternator

EMP 471007 Wiring Harness
Alternator Dual Connector
The EMP 471007 is the wiring harness connector for dual alternator setups on Marine Power engines. Dual alternator configurations are used on higher-demand marine applications where a single alternator isn't enough to keep up with the electrical load from electronics, refrigeration, lighting, and other onboard systems. This connector is the harness-side plug that interfaces with the dual alternator assembly.
If the connector is damaged, melted, or corroded, replacing it is a straightforward fix that restores a clean electrical connection without splicing into the harness or replacing the alternator. A poor connection at the alternator plug can cause undercharging, intermittent charging faults, or voltage drop issues that are easy to misdiagnose as an alternator or battery problem.
This connector is specific to dual alternator applications on Marine Power engines. It is not the same as the single alternator connector. Confirm your engine is equipped with a dual alternator setup before ordering.

The Sierra 18-99445 is an engine adapter harness designed to bridge older Mercury engines that use a side cowling connection to a newer 8-pin plug configuration. If you're repowering a boat with a newer Mercury engine or upgrading a control harness, this adapter saves you from having to rewire the entire setup. It connects the old side cowling connector on the engine side to the modern 8-pin plug on the rigging side, making the two systems talk to each other without cutting or splicing.
This is a practical solution for repower projects and older Mercury engine upgrades where the original harness connector style no longer matches the new equipment.
