Exhaust flapper

[Carrera205]

How hard is it to replace this. How do I go about it.

 

[Shlbyntro]

Pretty easy. It's just somewhat time consuming. Sometimes but it looks like you already have the hard part taken care of (getting to it). Once you get the boot off of the y pipe, generally the pin and or retainers will just pop out. Sometimes you will have to gently persuade them with a screwdriver and a small hammer.

What's this in? Looks like an omc/Volvo styled shutter??

Its in a merc 350. That's a photo from the rear of the boat in the exhaust tip. I have'nt taken off any exhaust boots or anything yet.

Gotcha. If it's a thru transom tip, they are sometimes welded in. It's almost cheaper and easier to replace the whole tip or throw a rubber flapper on the back if you have a straight cut tip. Some companies offer rebuilds on their tips like Hardin I believe

I've always taken them out of my boats, all they do is rattle around and make noise especially when the rubber comes off the tips/ends.

Would that be a gayliner with a big block

I've hydro locked this engine before shutting off the ignition when a wake came up behind me so I think they are important.

Thats's what I was thinking unfortunately. They are slash cut but I'm thinking of replacing them with straight cut and putting the rubber flap on the outside for future ease.

I've replaced those before, they aren't bad. Sometimes they are welded in, yours are not. Yours have two small brass pieces on each side that press into two holes and those hold the flapper in. You should remove the exhaust tip, then you can drill or hammer out those brass pieces and finally the flapper will come out. To reinstall you install the flapper and put the brass pieces in each end and press or hammer them on. Make sure to install the flapper with the beveled edges facing the outside of the boat. Imco sells the style flapper you need.

Sorry, I've never had a small block in a boat before.

They make these, never used them, but might be cheaper then replacing the tips

With good external flappers you don't need the internal flappers also.

I see this flapper thread turning into a train wreck based on some new poster we got ...

Are you compensating for something

Are we still talking about boats?

No, I like my motors to match my dick.

Yeah, I think the outside ones are called labia majora.

These guys have a bunch if different options, if you're going with the external Salisbury flapper u can always do what I did and cut your slant tips off straight.

Hell ya thank you!

Yes. If you are concerned with water getting in through the exhaust cut the internal ones out and put exterior flappers on there.

Yeah I was saying if the ones I currently have are welded in Ill replace with straight tips without a flapper and buy the rubber external one. But since they aren't welded in I don't have to go that route.

I did that to one of mine and finding new ones was almost next to impossible because they were made by Rex Marine and they are no more.

Yeah Im starting to lean towards cutting the angle off with a cutoff wheel and using the rubber flapper. Done and done no disassembling the exhaust.
