Parts Player Marine Starter for Mercruiser 3.0/3.0LX (1996–2004) — 12V Gear-Reduction, 1.4 kW, 11-Tooth

Parts Player PH140-0017-D is a new 12V Delco PG260G permanent-magnet gear-reduction starter engineered to replace original direct-drive units on many Mercruiser 3.0/3.0LX and related engines.

This starter is a drop-in replacement option for a wide range of Mercruiser powerheads and related GM-based marine engines from the mid-1990s through the 2000s. It delivers 1.4 kW of cranking power, clockwise rotation, and an 11-tooth drive, and is built to the PG260G unit series specifications. Because it uses gear reduction, it can offer improved engagement torque over older direct-drive starters—but correct bolt length and mounting alignment are essential for proper fitment.

Which Mercruiser engines will this starter fit?

This Parts Player starter is listed for many Mercruiser and GM-based marine applications. It covers 3.0/3.0LX models from 1996–2004 and numerous 4.3L, 5.0L and 5.7L variants across model years in the late 1990s and early 2000s. Always verify cross-reference numbers and engine model codes against your boat's serial plate or OEM parts diagram.

• Primary fit: Mercruiser 3.0/3.0LX (1996–2004)
• Also compatible with various 4.3L, 5.0L, 5.7L Mercruiser/GM-based engines (see fitment list)
• Cross-references include PH140-0017-D, PH1400017D, ST95, LRS01796, 863007A1 and more
• Check your engine code and replacement part numbers before ordering

What technical specs and hardware differences should I know about?

The unit is a PG260G series permanent-magnet gear-reduction starter: 12V, 1.4 kW, clockwise rotation, with an 11-tooth pinion. Because it replaces older direct-drive starters, the mounting bolt length and spacers used on the original may not be appropriate; shorter bolts designed for PG260 series gear-reduction starters are required for correct alignment. Mounting hardware is not included.

• Voltage: 12V; Power: 1.4 kW; Rotation: CW
• Pinion: 11 teeth; Unit series: PG260G (gear reduction)
• Mounting bolts: use shorter PG260-specific bolts; do not stack spacers
• Mounting hardware not included — purchase or reuse correct bolts

How does this starter compare to OEM or other replacement part numbers?

This Parts Player starter cross-references many OEM and aftermarket numbers, making it a practical substitute for units listed under older direct-drive or other part codes. Its design matches SAE J1171 compatibility for specified Mercruiser models, and a wide range of catalog numbers are provided so you can confirm compatibility with your original starter. Note that fitment confirmation prevents alignment and engagement issues.

• Cross-listed to dozens of OEM and aftermarket numbers (see feature list)
• Meets SAE J1171 compatibility for specified Mercruiser applications
• Designed as a gear-reduction replacement for older direct-drive starters
• Verify original part number and engine details before installation

What should I prepare for installation and maintenance?

Installation requires verifying bolt lengths and ensuring the starter aligns with the flywheel ring gear; incorrect bolts or stacked spacers will cause misalignment and premature wear. Because mounting hardware isn't included, have suitable PG260-series bolts on hand or order them separately. Routine inspection of electrical connections and the pinion engagement will extend service life.

• Confirm bolt length and starter face-to-flywheel clearance before fitting
• Order PG260-compatible mounting bolts if originals are too long
• Check battery, ground, and solenoid connections during installation
• Inspect pinion and ring gear engagement periodically for wear

Who is this for: This Parts Player PH140-0017-D starter is aimed at boat owners, marine mechanics, and fleet maintainers who need an affordable, OEM-cross-referenced replacement for Mercruiser 3.0/3.0LX and many related GM-based inboard/outboard engines. It's appropriate for anyone comfortable verifying engine model codes and replacing starters where a gear-reduction unit is acceptable—provided they prepare the correct shorter mounting bolts and confirm fitment against the comprehensive part-number list.
