Engine & part-number match
Delco-style gear-reduction marine starter listed under RA122009, with a 9-tooth pinion. This is the GM left-hand application listing. Confirm the current starter reference, rotation and mounting before ordering, particularly if the engine or starter has previously been changed.
Before ordering
- 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 is the top-mount starter reference; RA122015 is a separate bottom-mount assembly. Confirm mount and engine rotation.

Fitment & setup
Which references distinguish this starter?
The listing references RA122009, Crusader 42091 and 42150, Indmar 57-3001, Volvo 3862985, and Delco 9000888 and 19010615. Use the number on the existing starter to request an exact replacement check.
Is it interchangeable with the RA122008 starter?
Do not substitute the two based on similar appearance. Confirm the required rotation, pinion and mount with GT40 using your existing part number and engine information.
