Marine engine parts
Match the part to your engine.
Use the engine model and serial number, the complete number on the installed part, and its mounting or connections. A boat year or similar-looking component alone does not establish compatibility.
This GT40 selection checklist summarizes the product references below. It is not an installation procedure or a complete manufacturer parts manual. Refer to the instructions for your exact engine before starting work.
RA122019 bottom-mount starter
PCM lists RA122019 as the starter motor assembly in the MP6.0L MY2007 manual. Confirm the installed starter, mounting and engine serial; this reference does not establish every Indmar application.
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Starter mount, engine rotation, terminal arrangement and flywheel configuration.
RA122009 top-mount starter
The MP5.0/5.7L manual distinguishes RA122009 top-mount from RA122015 bottom-mount starter assemblies. Match the mounting arrangement and complete installed reference.
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Starter mount, engine rotation, terminal arrangement and flywheel configuration.
RA080018 low-pressure fuel pump
The manual identifies RA080018 as the low-pressure supply pump and RA080025A as a separate high-pressure pump. Identify which component your engine needs before choosing a replacement.
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Fuel-system revision, pressure role, connector and hose/fitting sizes.
RP061017 raw-water pump impeller
The manual lists RP061017 for the belt-driven or crank-driven raw-water pump, and RP061022 for the serpentine arrangement. Match the installed pump and drive arrangement.
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Installed pump number, drive arrangement and impeller dimensions.
RP080026 fuel-cell filter and O-ring kit
RP080026 is the Fuel Control Cell filter-and-O-ring kit reference. Match the installed FCC revision and verify the supplied seals on the exact product listing.
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Fuel-system revision, pressure role, connector and hose/fitting sizes.
R130011 fuel-pump relay
Keep the full relay number, including its suffix. The documented RA121079A harness calls for R130011A; a listing that says R130011 does not by itself establish that revision.
- Engine model and serial number.
- Complete installed relay number, including any suffix.
- Harness reference, connector and terminal arrangement.
RA080025A high-pressure fuel pump
RA080025A is the high-pressure pump inside the listed Fuel Control Cell assemblies. It is separate from the low-pressure supply pump and from the complete FCC assembly.
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Fuel-system revision, pressure role, connector and hose/fitting sizes.
Reference scope: PCM MP5.0/5.7L parts manual L510013 and MP6.0L MY2007 parts manual L510014-07. The cited assemblies identify specific components; they do not establish universal interchangeability or what a GT40 order includes. Ask GT40 for help with your exact part and engine if the match is unclear.
