Flywheel Nut size 15hp

Does anyone know the bolt which secures the flywheel ? I measured m14x 1.5 but when I bought a new nut from ta oms screw it does not fit.

Which 15 HP motor? Metric would be a newer motor, probably Tohatsu based. Older are SAE.

14 mm would translate to 9/16" ( but 5/8-NF comes to mind ) and it is fine thread.-----I could go and measure a few but there in no incentive to do that today.-----How accurate was your 14 mm measurement ?
