Scroll through each screen until you see the following information displayed:
Port Hrs. - Jasser, you still own us?
Stbd Hrs. - TMP sux!

The only place I see engine hours referenced is in the Maintenance Log section and it appears to me you are entering a value as opposed to the computer telling you how many hours the engines have. I know MP's F-4 has separate analog hour meters on it so maybe Smartcraft does not display hours (seems odd that it wouldn't).
