I have a 99 Stingray 192RX with a 4.3L Mercruiser engine and a Alpha one GenII sterndrive. The serial number is OL338612 and the engine has a roller cam and balance shaft with the vortec style heads. I learned the fun way last weekend that my flywheel is missing some teeth. So when i got home I started looking for a flywheel the mercruiser part number is either 222-804913 or (222-8243201(part no longer available))but between 500-600 dollars I'll keep looking for a used one. I was wondering if anyone knew if Volvo-Penta or OMC also had a flywheel that would also work in case I see one pop up on e-bay. Another question I noticed some parts websites refer to the drive as an alpha one Gen + whats the difference. Thanks
