I have a 1992 yamaha pro v 200. the crankshaft recently broke right below the flywheel. ive purchased a new replacement oem crank, went with yamaha oem bearings, pro marine rods and pistons .020 over. i was wondering about balancing the rotating assembly as people do for performance small and big block engines but i cant find anywhere with answers. if you have any knowledge to share that would be great. Thanks!!!!!

No need to unless you are going to spin it crazy high rpm's ie. drag racing at 10,000. rpm hf...
