Clean out plug actually filled with water?

[haknslash]

I get water in the plugs and on top. I took the hatch off and tightened every thing up ( the band band clamps) and resealed the hatch.
I still get water in my plugs and on top....but I get less water in my bilge when I pull the plug.
I would think the plugs only seal so well and would think there is a lot of water pressure pushing it's way into even the smallest area of the seal it can get passed. At this point I figure it is what it is and part of it is just the design and it's not that big of a deal.
My last boat was a 19 I/O.....kept the plug in most of the summer and never got more than an once of water unless I pulled in a soaking wet tube and it drained into the bilge.

Water shoots up to the swim platform wet storage and fills the water on top of the plugs because of the drain tube when coming off plane. There is no check valve in there. Add a check valve and it will prevent water from back flowing up the hose and into the storage compartment,

I was thinking that's a lot of water on a 2019 and your plugs shouldn't need rebuilt yet. I use a little white spray grease on the seals of my plugs...maybe yours are getting dry and/or have some sand in there thet's not allowing a completely clean seal. Like others have said, maybe this water is coming up the drain hose pictured above as well.

any idea what the ID of that hose is? 1 inch?

 

[haknslash]

Not clue since we don’t have the boat anymore. Removing the tray is simple though and they don’t seal it much at all.

I called the dealer today just to inquire about this. They first brought up water coming over the back but I told them I sat on the back of the boat and held the kill switches and watched them fill. The seal kits are only $48 a side so I will give that a try and seal up the back area. I have a 01 LX210 and no water ever came up through the clean out plugs. I should of taken a video of it while I had it out. When accelerating no water would fill, it was not until I got on plane and let off the throttles that they began filling. My guess is that is when the impeller stops pulling a vacuum on the intake side and it build pressure because the boat is still moving forward and water is pressurizing the water intake area. That pressure then seems to fill up the plug holes.

That’s good info. I did a rebuild on one of mine because the rubber swelled from being left in. It didn’t make a difference with water passing by.

 

[LX210]

Interesting. I wonder if there is a way to modify the twist mechanism to push down further or seal better.

 

[dshscarab]

I actually replaced the seal on mine too for that very reason. I have a 2019 AR195 with 52 hours on it. After replacing it, it did help a little bit. Is it possible that it contributing to cavitation that most single engine owners have experienced?

 

[LX210]

It’s on the intake side of the pump so definitely could contribute to that problem.

 

[dshscarab]

I would think that if it develops enough force to blow by then it could create enough suction to cause cavitation. Now, the big question is, how do we fix that without permanently sealing it??

 

[Cambo]

The leaking seal should not cause cavitation its filling with water if it was bone dry pulling air in that could possibly cause cavitation . I did extensive work on the clean out area to keep water out of the entire tray my problem was the water spills into the bilge and its salt water pouring all over the hose clamps etc. it stays very dry now

 

[tdonoughue]

Respect to those who are trying to keep this area dry. But, from the original perspective, was this not called 'wet storage' for a reason?

For my money (and I may be completely wrong), I am worried not worried if there is water in wet storage. I am worried if that water makes it to the bilge rather than down the drain to the outside. To that end, I have focused on sealing the cleanout tray. Am I missing something here?

Yeah I agree with this. That is where I concentrated my efforts, sealing up the cleanout tray. It seems to be normal for the new style clean out ports to have water in them after day on the water. However, it is getting there from my observation on this forum everyone has it. So far from my experience and from what I've heard from others it is not an indication of anything wrong and does not have any adverse effects as long as the tray is sealed. Personally I seal up the tray and stopped worrying about, it hasn't affected any of the boat's performance, top speed, etc.

 

[haknslash]

Yes that area is called the wet storage area and it does have a drain. The problem though is poor execution from Yamaha. As we all know it’s not really a sealed compartment and the drain hose does not have a check valve. Every time you come off plane the water will rush up through the hose and begin spraying in the wet storage compartment. Ever wonder why the underside of the hatch ALWAYS has water on it? Yea it’s because it’s sprays out of the drain. Some of the water fills the cleanout plugs and around the tray then overflows into the bilge. The added problem with all of that is the bilge pump is not in the actual bilge but rather in the engine compartment which is higher than the bilge. Imagine if your were at s dock and a storm rolls in with your stern facing the waves bashing in. It could cause enough water to fill the bilge. I think someone on here even had a scenario like that happen and they were puzzled how water got into the engine area. That’s how it happens IMO. So yes it’s a wet storage but it’s poorly thought out. IMO if you want a dry bilge you add a check valve to the drain hose and you seal the tray.

I’m fine with it being wet storage but just to give you an idea of how much water can dump down into the bilge area stuff a cork in the drain and fill the tray with water . This will also give you an idea of how well the clean out plug seals or seal are operating . Once the two tubes fill the tray fills if the drain plug is out in the hull water flows out at an alarming rate . The oval inspection hatch in the tray looks like it could seal out water it does not at all the water can pour through that faster than the drain will allow water to escape and the drain lets water come in . The older hull design was different and after daily use when the hull drain plug was pulled a small dribble or nothing came out . The new design a gallon or more would come out until this area is sealed up . The clean out plugs stay dryer unless we are doing excessive starting and stopping during water sports or surfing

I know this is an older thread but has anyone bought and installed a check valve in the drain hose?

I have not tried that. I just pulled the clean out tray out and put new caulk/sealant down so it wouldn’t leak Into the hull. So then it’s really not a concern how much water is in there.

 

[Ibeflyinhigh]

There is usually 5 inches or so on top of the starboard one. But I actually have water inside the plugs themselves which is more of a concern I think.

I can tell you after pulling out of the lake I idled my engine and rev'd it a few times to blow all the water out. When I got home I removed the clean out plug(no water on top of the plug) and a bunch of water came pouring out under the boat. I think it's normal and yes it can freeze so I remove my plug after every outing.

 

[tdonoughue]

Slightly confused here... You had no water on top of the plug, but when you pulled it water came out the bottom of the boat?

I remove my plugs every time (and have had no issues with them sticking or corroding). I usually have some water on top of the plugs, and when I pull them it goes rushing out the bottom. Perfectly normal as far as I am concerned. But if there was no water on top of the plug... where did the water come from that was pouring out the bottom?

Are you sure there was not water on top of the plug? At least a little bit?

That's correct. No water on top of my clean out plug and when I removed it about 4 to 5 cups of water splashed all over my garage floor. I thought it was strange too.
