Water coming into engine compartment under power. See pics.

Do this - put your camera in the exhaust compartment, put the cleanout lid back on, and then (with engines off, but cleanout hatch open), hose down that cleanout tray - 100% chance it's leaking like an SOB.

So we did that exact thing a few weeks ago. (I even sang the OSHA violation song) Only moving at a few mph. Basically just enough RPMs to replicate the water intrusion. It oozes up between the two fiberglass pieces shown in the video. I cannot see any hoses in there or any that runs there.

I had it hooked to the hose just now and ran the motor and didn't see any leaks. I have very high water pressure and it was "peeing" and pouring out the exhaust at a very good rate. However, I forgot to increase RPMs to see if it will do it. I'll go rehook it up and do it again.

I'm not sure of your directions. Hose down that stern area where the clean out tray is while my phone records the exhaust? What is the exhaust compartment?

Do you mean water rushing in like when I stop and the wake washes over the stern? I've sealed that every time I removed this tray with the screws. I'm sure water gets in from the removable hard plastic tray with the handle, but that's not where the water is coming from. The very first video I posted shows the water being forced in from under the fiberglass that the engine sits on and above the hull.

My guess is you have a hose leak....can you get your wife to drive the boat again while you have the clean out tray off (not that I'm recommending you violate OSHA regulations-but you did it already....this is dangerous....don't ever take my advice!) and use your phone to inspect every hose connection back there! Its clearly coming in under pressure.

Does it get water when you run it on the hose? If so, then its not the shaft hose seal, or the bearing. The problem with this is you might not have enough water pressure to replicate the in water pressure-so its not a definitive answer, but helps some.

We did that a few weeks back, that's when I confirmed where water was rushing in. No water came from the hose while running and some RPMs. I did however record and saw a little bit of dust or something blow past the camera when I bumped the throttle. Is there a seal or something within the jet propulsion that sits under that fiberglass floor the motor sits on and above the hull? I've seen what normal seal failures look like. That's crazy and scary with that much water being sprayed everywhere.

Do it at the dock first. Increase rpm to 3500 while on neutral, well tied to dock, and you might just see it without having to do acrobatics.

I thought I replied to this a long time ago but I don’t see the post anywhere. My boat was bringing in water in that same area you’re mentioning. It turned out to be the hose clamps that secure the clean out tube to the lips of the molding at the bottom. It was not secure. There’s a clamp at the top and bottom of the tube. The one at the bottom climbed up the tube instead of tightening around the lip which left a gap for the water to go through. You’re saying your water is warm, so this may not be the problem. But the symptoms are the same as what I experienced so thought I should mention it.

Starting at 56 seconds in your video in post 21, it looks like your exhaust is not connected to what looks like your water locker.
At about 5 seconds in your video in post 18 the red fiberglass looks burned possibly from hot exhaust gasses?

He's referring to the clamp in this photo.



My only question about that is that this would mean your clean out plug is not seated properly (if its coming through under pressure).

All your videos point to a leak, under pressure, from a cooling hose under the clean out tray, not in the engine compartment.

I dropped the boat off at a dealer for them to figure it out. There are no leaks from any hoses in the clean out tray/bag area. In that most recent and longer video I shared in post #21 was to show no hull leaks with the boat filled with water. The clean out port twisty thing doesn't leak. The water intrudes where the jet pump housing is. I think it may be cracked somewhere. I hope there is some hose or clamp etc that's an easy fix as the shop has a $120hr labor charge! Probably looking around 4k for this repair if it's the jet pump housing.

The stealer-ship will most likely not water test it change some parts bill you and when you put it back in the water it will still get water in the hull.

I will double check what you said to look for

Did you plug the drain hole and fill the clean out tray with water ? Below is what you will see that is one of the main causes of water coming in rain water also gets in even with the cover on.

Which dealership did you drop it off at?

I pulled the boat from the dealer. I've since moved and they had the boat for several weeks and didn't even get a chance to look at it.. looks like back at DIY. I believe the jet drive may be cracked somewhere.

Going to pull the motor and take a looky lou
