A poppet valve is a pressure relief valve and Yamaha seems to be the company that named it a "poppet". Evinrude calls theirs a pressure relief valve or a "blow off" valve.


from a previous post:

Your cooling system should be checked out completely and the temps tested per service bulletin 2005-05 S. Your tech can also call dealer service hotline on how to check, repair, or replace a problematic "blow off" valve assembly.
