I do it religiously on omc big twin 25-40 hp’s. Just did one last weekend. I learned the very hard way. Sheared two keys on a 57 35 while on a vacation. These guys have me the knowledge…..thought I could get away with "winging" the torque on a 1956 30 that was a Frankenstein motor. Sheared the key on first run and took the top of the crank out.
Never skip it on a new old motor now and ALWAYS torque to spec.
