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.
