Hi Richard,
your flapper doors are very necessary to preventing hydrolock of you
engine. I lost an engine to an incompetent mechanic that decided in his
infinite stupidity, that flappers were not necessary. It cost me a 7.4
engine and 2 weeks down time during the height of charter season.

before I went on a several week vacation on my boat,(1993 245vista
four winns, I/O)it started making this noise.the noise was metalic and
sounded to a novice like me that it was comming from the engine or
behind it. I took it to my mechanic afraid I had blown the engine or
something and he said it was the flappers, some rubber had worn away,
and not to worry.
ok, so I trust him as he did not try to fix something that didn't need
fixing, but I am not really sure what the flappers do. is this
something that I should get fixed sometime, is it something that I can
do? any info would be great
thanks
