Do I need an anti syphon valve?
Engine is Yanmar 3GMF with exhaust outlet 6" above the water 12" off centreline. Its never had one and never had a problem but most systems seem to have one.
Are they needed?
Only seem to cause a problem if they jamb open and let sea water into boat.
Can't see how an engine would flood by syphon anyway.
I want to keep it simple but am I risking it.
