Starter Drive for United Tech Marine Starters - 13-Tooth CCW, Large Spline
13-tooth CCW large-spline drive for United Tech Marine starter motors
A starter drive engages the flywheel ring gear when the starter motor spins and disengages once the engine has fired. This replacement is built to a 13-tooth, counter-clockwise (CCW) specification with a large-spline pinion, matching the drive fitted to United Tech Marine starter motors.
The large-spline pinion design means this drive is intended for United Tech Marine starters using a wider shaft spline than the standard drive - check your original drive's spline size against this listing before ordering. It is compatible with United Tech starter units including part numbers 5274040 and 5676940.

Frequently Asked Questions
Will this fit without modification?
Yes - this drive matches the 13-tooth, CCW, large-spline specification of the United Tech Marine starter motor. Confirm teeth count, rotation and spline size against your original before ordering.
What's included?
This listing is for one replacement starter drive only. The starter motor itself, mounting hardware, and battery cables are not included.
How do I know my starter drive has failed?
Common signs include the starter motor spinning without turning the engine over, a grinding or clicking noise on start-up, or the starter remaining engaged after the engine has started.
What does 'large spline' mean?
The spline is the ridged section of the shaft that the drive slides onto - it must match the size on your starter motor's armature shaft for the drive to engage correctly. Compare the spline size on your original drive against this listing, and check it against United Tech part numbers 5274040 or 5676940 if known.
