Engine & part-number match
RA122008-referenced Delco-style gear-reduction marine starter. This listing specifies clockwise starter rotation and includes the Crusader 42090 reference. Confirm the exact rotation, mounting arrangement and existing part number before ordering.
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.
Exact replacement needs confirmation. Use the checks above so GT40 can confirm the correct part.

Fitment & setup
What should I compare with my current starter?
Start with the starter label, required rotation and mounting face. The listing includes RA122008 and Crusader 42090 references; GT40 should confirm the replacement against your exact engine and installation.
Does a 454 engine automatically mean this is the right starter?
No. The engine size alone does not identify the starter rotation or mounting arrangement. Send the current starter number and photos to support@gt40marine.com before ordering if the match is unclear.
