Ironic you should mention that. They have this newsletter on their site- topic is broken snouts.

Hey Jay!

I've seen some high quality cranks (Lunati, Callies) break off at the snout too if the blower belt is too tight. There isn't any give in a toothed Gilmer belt.
I know on my own boat with 671's and Superchillers, there is a LOT of growth as the motor heats up. When stone cold if the tension is set at 1/2" play, the belt is tight as a banjo string when things get hot. If your not consistantly checking blower belt tension to get a feel for where it needs to be when cold, somethings gonna give.

See ya in the spring!
