7.4 MPI Gen VI ring gear part number

[Mischief Managed]

The ring gear on the flywheel of my 2000 7.4 MPI is worn in spots and needs replacing. Mercruiser only sells the flywheel, but I know how to change the ring gear on a lywheel and can likely save 500 bucks by doing so. Does anyone know a part number for the ring gear alone? Does not need to be a mercruiser part number. I think it's a 14" flywheel and will accept Sierra part number 18-4516, but I'm not sure.

Don't know the GM part number but a 14 inch fly wheel should be 168 teeth. All the 14 inch GM fly wheels use the same ring gear.

Ebasic power part number is BPIRG-168-S

14" flywheel and will accept Sierra part number 18-4516, but I'm not sure.

Looks like the Sierra number will fit too.

If interested, I believe if you call iboats and ask about the forum5 promo code discount, it may apply to this item as well. (14" GM flywheel w/ 168 teeth)
