My 36 has a Vetus Waterlock exhaust system component in place of the muffler. It does not have a drain valve on the bottom like other muffler systems. I have had an engine problem resulting in excessive cranking without starting. I have read that I need to drain the excess water out of the muffler before starting or bad things will happen.I have the manual on this part, but it does not show any drain valve. I will try contacting the manufacturer, just wondering if anyone else has any info on this situation.
