Here are the turn-downs that I had on my boat. They are for 4.5" exhaust.

Today I recieved an email from the ex owner of my boat :
Hi Michele,
you have the flaps inside the mufflers and you want to add flaps on the outside ?
I think, its to much backpressure for the engines, they will runing to hot and will not have the full power !!!
Dont do this, the mufflers are enough !!!
as you can see on the picture you sended me, the flaps are fixed on an exhaust pipe and not on a muffler !
Belive me, flaps and mufflers are to much for the engines.Try to go full thottle with the mufflers closed, you will loose about 300 RPM and the engines are running to hot.
Greetings
Kurt
What do You think ?? Is he right ??
The only thing..it's I'm a little bit scared from the waves that we have in our seas....and the risers are not so high .....

I had the internal muffler flaps on a 96 Topun and they let water in to ruin a motor. Mercury as well as TNT told me that the outer rubber flappers are the way to go to play it safe.
