Found this in my bilge, any ideas?

[VitaminSea]

I installed a stainless drain plug and while doing so I noticed a piece of a hose clamp in the bilge. When I looked through the access hatch, I saw this...


I was able to remove the broken clamp. It measures around 4 inches in diameter.
I checked the top and bottom of the two clean out port sleeves and they both have a clamp in place. All of the other obvious (to me) hoses have significantly smaller clamps

I also noticed that I should consider replacing the clamps when I instal my second bilge as they have show some rust. Any suggestions on where to source? I recall some post about supposed SS clamps that rusted in short order..

check exhaust hoses

Next time I am at the boat, I will take another look around in the bilge. I might need to resort to removing the entire access tray for greater visibility. I have read that can be a bear.

yes but the back clamps are notorious for rotting and falling off so you need to check them I always add a heavy cable tie next to the clamps for extra security since you don't want carbon monoxide in the hull or water from the exhaust

Just to confirm, I would be looking for what is tagged as #4 on the diagram.

That could also be a clamp that secures the cleanout plug tube to the access tray under the cleanout hatch Or the clamp which secures The tube to the pump. Parts 10 and 11 in this pic.

Thanks for the feedback. That was the first place I check and each tube has a clamp at the top and bottom, which are showing some corrosion and need to be replaced in the not too distant future.

I’m also trying to figure out if I should replace with OEM, or if there is a more durable SS Clamp I should consider. Now that I know about CorrosionX, I will be sure to treat the new clamps once they are installed.

I bought a bunch of replacement clamps from west marine. I believe they are SS, they were about twice the cost of those sold by yamaha sports plaza but I shouldn’t have to replace them again.

yes there the clean out ports are a lot bigger than 4 inches

Made it back to the back today to perform an oil change and plugs. Took a look through the small hatch, and it appears as if both clamps for the starboard exhaust are GONE!

@Cobra Jet Steering LLC , Jeff, thanks for the heads up here. Much rather discover this while safe on land vs out on the water, although it probably broke off during the last outing.

So now I need to determine how to access this and replace the clamps. It would appear that even after removing the larger tray, it’s going to be a tight squeeze to get clamps installed here. I image this has been done before, so looking for any advice.
