Frequently Asked Questions
What is the difference between OEM and aftermarket marine parts?
OEM parts are produced by the original engine manufacturer. Aftermarket parts are replacement parts produced by other manufacturers to fit the same application. Pro Marine provides quality OEM specification aftermarket products for marine maintenance, repair, and rebuild applications.
How do I find the correct inboard or sterndrive parts?
Use your engine model number, serial number, drive model, and horsepower information to confirm fitment. Sterndrive applications may also require the drive serial number for accurate parts matching.
What brands are included in this category?
This category includes Mercruiser, Volvo, OMC, Crusader, Pleasurecraft, Indmar, and Chrysler marine engine applications.
What are common signs my sterndrive needs service?
Common warning signs include overheating, water in gear lube, vibration, difficult shifting, drive noise, poor acceleration, bellows leaks, and excessive corrosion.
Are aftermarket sterndrive and inboard parts reliable?
Yes. Quality aftermarket marine parts are commonly used by marine mechanics and rebuilders. Pro Marine offers OEM specification aftermarket products for many marine engine and sterndrive repair applications.
Tip: Before ordering sterndrive or inboard parts, verify the engine model, serial number, and drive model information whenever possible.

Manufacturer: Mercury Marine
OEM or Aftermarket: Genuine OEM
Applications: Mercury Outboard and MerCruiser
Outboard Families: Mercury, Mariner, Verado, Pro XS and Racing
MerCruiser Applications: Sterndrive, Inboard and TowSports
Original OEM #: 8M0052939
Current Replacement #: 8M0207794
Mercury Marine has superseded 8M0052939 to 8M0207794.
If you order the current genuine Mercury replacement, the part may arrive under OEM number 8M0207794 and may look slightly different from an older 8M0052939 switch while serving the same specified replacement application.
Compatible Applications
Mercury 8M0052939 / 8M0207794 is used in a broad range of Mercury Marine shift systems. The supplied Mercury fitment includes outboard, Verado, Pro XS, racing, sterndrive, inboard and TowSports applications.

View Pro Marine 52939P Neutral Safety SwitchWhat This Part is Used For
The neutral safety / shift position switch provides the engine or control system with information about the position of the shift mechanism.
On applications where it serves as a neutral safety switch, it is part of the starting-safety circuit that helps prevent the engine from starting while the transmission or gearcase is in gear.
Mercury also uses this switch in several mechanical and Digital Throttle and Shift (DTS) systems, which is why the same OEM switch appears in outboard, sterndrive, inboard and diesel applications.
Common Symptoms of a Neutral Safety or Shift Switch Problem
- Engine will not crank even though the control is in neutral
- Intermittent no-crank condition
- Engine starts only when the control lever is moved slightly
- Incorrect or inconsistent shift-position indication
- DTS or shift-related fault after other causes have been eliminated
- Physical damage to the switch or actuator
- Corrosion or damage at the electrical connector
These symptoms can also be caused by wiring, linkage adjustment, control-box problems or other starting-system components. Diagnose the system before replacing the switch.
Installation and Replacement Tips
- Disconnect battery power before servicing the shift or starting circuit.
- Confirm the OEM switch number before removing the original part.
- Note the position and adjustment of the original switch.
- Inspect the electrical connector and wiring for corrosion or damage.
- Inspect mechanical shift linkage for wear or improper adjustment.
- Install and adjust the switch according to Mercury service procedures.
- Verify proper forward, neutral and reverse operation after installation.
- Where applicable, verify the engine starts only in neutral.
- On DTS applications, follow the appropriate Mercury diagnostic procedure.

1/2" Type A1 Marine Fuel Hose
MPI 360-12 1/2" Type A1 Marine Fuel Hose
The MPI 360-12 1/2" Type A1 Marine Fuel Hose is a heavy-duty bulk fuel line for marine fuel systems requiring a 1/2" inside diameter and the additional fire-resistant protection associated with Type A1 marine fuel hose.
The larger 1/2" inside diameter makes this hose suitable for higher-flow marine fuel-system applications where a larger supply line is required.
Pro Marine stocks the matching German-style hose clamp, installation tools and a complete clamp assortment for marine fuel-system service.
Inside Diameter: 1/2"
Manufacturer: MPI Products
Fuel Hose Type: Type A1
Application: Marine Fuel System
Matching Clamp: German-Style Hose Clamp 4-4
What is Type A1 Marine Fuel Hose?
Type A1 marine fuel hose is designed for fuel-feed applications requiring a marine hose with enhanced fire-resistant performance.
Type A1 hose is commonly used in permanent marine fuel systems and installations where the fuel line passes through enclosed or below-deck areas.
When selecting fuel hose, both the inside diameter and the required hose classification should be verified for the installation.
Why Use 1/2" Fuel Hose?
A 1/2" fuel line provides greater internal flow area than the more common 1/4", 5/16" and 3/8" marine fuel hoses.
It may be used in applications where the engine or fuel-system design requires a larger fuel supply line to support higher fuel-flow demand.
Always follow the engine or boat manufacturer's required hose diameter rather than increasing or decreasing hose size without verifying the fuel-system requirements.
Unlike many smaller outboard fuel-line assemblies, a 1/2" marine fuel-line system would not normally use an inline hand primer bulb.
Larger 1/2" fuel lines are generally associated with higher-flow fuel systems where fuel delivery is handled by the engine's fuel-system configuration rather than a manual primer bulb.
Always follow the fuel-system design specified for the engine and boat.

View Oetiker Clamp PackWhat This Fuel Hose is Used For
MPI 360-12 is used when building, repairing or replacing a marine fuel supply line requiring 1/2" Type A1 hose.
Typical applications involve larger marine fuel systems where increased fuel-flow capacity is required and the installation calls for Type A1 hose.
Typical 1/2" Fuel-Line Setup
Depending on the boat and engine, a 1/2" marine fuel-line installation may include:
- MPI 360-12 1/2" Type A1 marine fuel hose
- German-style 4-4 hose clamps
- Fuel tank pickup or shutoff valve
- Fuel/water separator or filter assembly
- Engine fuel-system connection
- Application-specific fittings and adapters
Primer Bulb vs. Larger Fuel Systems
Smaller outboard fuel systems commonly use 1/4", 5/16" or 3/8" hose with an inline primer bulb.
A 1/2" fuel supply line generally indicates a higher-flow fuel system, and a hand primer bulb is not normally part of that configuration.
The engine manufacturer's fuel-system requirements should always take priority when determining hose size, fittings, filters and priming components.

FAQ
What size is MPI 360-12?
This fuel hose has a 1/2" inside diameter.
What type of fuel hose is 360-12?
It is Type A1 marine fuel hose.
What is Type A1 fuel hose used for?
Type A1 is used for marine fuel-feed applications requiring the additional
fire-resistant performance associated with Type A hose.
Can this hose be used below deck?
Type A1 hose is commonly used in enclosed and below-deck fuel-system
installations when the fuel system calls for this hose size and classification.
Which clamp fits this 1/2" hose?
Use the
German-Style 4-4 Hose Clamp
.
Does this hose use an Oetiker ear clamp?
The recommended clamp for this hose is the
German-style 4-4 hose clamp.
Does 1/2" fuel hose use a primer bulb?
A primer bulb is not normally used in a fuel system
requiring 1/2" hose. Larger lines are typically used in higher-flow fuel
systems with a different priming and fuel-delivery arrangement.
Should I use 1/2" hose just to increase fuel flow?
Use the hose diameter specified for the engine and fuel system. Increasing
hose size without verifying the complete system is not a substitute for
following the manufacturer's fuel-system requirements.
