here's the scoop Stock Mercruiser 350 MAG MPI and the MX 6.2 377 and the 377 MAG MPI and the reman 383 MPI and the reman 385 Performance tune all use the same flywheel. It is currently the exact same part # thru all the serial #'s for each model. Currently the crankshaft for the newer 350 MAG MPI and Catalyst is NOT AVAILABLE but the all 377 - 6.2 crankshafts are still available with updated part #. MERCRUSIER flywheel part # currently is 2228M0047213 good luck and I hope this helps. I can get it for you if needed and will sell at a reduced price but will make some off of you.

Motor,

I sent you a link to a NOS 2228M0047213 / 14091599 to used as a reference for purchase. The crankshafts are still available at a greatly reduced price from the original OEM supplier Lunati.

Good info and thru Mercruiser the 6.2 -377 crankshafts is available but the 350 MAGS crankshafts thru Mercruiser currently is NA.

Bob if you get a chance can you send me the links for the flywheel and the Lunati part # for the cranks. Thank you very much.

So I decided to go and look up part #'s on bam marines site .Just about every small block I pulled up had the 8M0047213 FLYWHEEL 222-9520 $591.75 $521.57 .That included 5.0 5.7 and 377 from 1987 ...What am I missing

Not to spam, but offer if it helps, I've got a 350 crank I'll let go cheap. Came out of a MasterCraft with the LTR motor. Crank is identical to my original 350 Mag crank. Motor had the same cam too. No flywheel though.
