Torque Spec on the Flywheel for a chrysler 557hd sn#1444 outboard??

[SICKOFIT]

Hi just picked up a sports satellite with a 55 hp outboard chrysler that sheared the flywheel key i have been reading and it appears i should have torqued the flywheel back to spec. Im ordering a book right now but was going to a merc dealer to pick up a new key so i have been read on here i can get and it should work 28-f92498 if i am mistaken any correction would be appreciated. The main question i have is the torque value on the flywheel if i could get that while im waiting for my book would be appreciated thanks for any help.

I have found a torque value of 80 foot-pounds for the flywheel nut on the 55 hp. Can't help with the key p/n though.
