7.4 crusader motor losing antifreeze

[lakesidevu]

My crusader 7.4 motor is losing antifreeze.

It is a 2001 all freshwater hours,less than 500.

This is my first season with this boat

No signs of any liquid in the oil,and no apparent leaks,no antifreeze in the bilge.

I'm not sure if the head gaskets would be a potential issue.

The motor runs fine at all RPM's

Any ideas on what to check?

Thanks for you ideas or feedback
