Flywheel for 2000 Mercruiser 4.3 v6 vortec engine
 

Im looking to buy a Flywheel for the above mentioned engine, but I'm not sure which one should I get. A lot of places post the flywheel for this engine but I hey all have different part numbers even when using GM casting. I saw 200-8M0083287, Sierra 18-4521, 222-9520, 222-952001, 14103283N ( this I'm pretty sure is for prevortec v6, 4.3). So I'm lost, can anybody tell me exact part number and could this flywheel be interchangeable with any other engines, like 5.7L or 5.0L v8? Thx

D,
What is wrong with your present flywheel ? If it just needs a starter ring gear they are easily available.

If you do not have a flywheel at all I would probably see if you can get a Mercruiser part number that matches your engine number. Then go from there. Not sure why but in a few of my listings the 4.3 flywheel is a different number than the 5.0 / 5.7 for that year.

probably has something to do w/ it being an odd firing engine.also,look for a p/n w/ N at the end,,stands for nodular,much stronger than stock.

2000 year model was vortec . I have new and used flywheels in stock
