Taking on water

On my 01 GTX RFI. Jet pump rebuilt over the winter. New wear ring. It flies, now. Massive hole shot, you better hang on. 54 mph top speed, all running great. This weekend had first heavy use since the rebuild. It is taking on water faster than the bailers can remove it. 20 minutes of riding and there is at least 5 gals in the bilge. Telltale is squirting like it should.

Tied it to the dock, revved to 3000. No leaks around the hoses, no leaks around the carbon seal. Can't see any source of water.

Water is hot and it is dirty. Not clear lake water. The heat could either be from the block itself or maybe from the exhaust? All the Welch Plugs are solid and no leaks. What about the water regulator? I can move it, rotate it by hand very easily. Is that normal? Would / could the water regulator leak at speed, but not at idle?

I will go back over the water circuit tomorrow, but if anyone has any suggestions, I am all ears.

Thanks and I hope everyone has a safe Memorial Day. As you're ready to bite into that hot dog, please take a minute to think about the reason for this season and thank those that served so we could have this fun.

Look into the case cooler on the bottom of the engine

Yea. On the RFI, the cooling hose runs into a stator or a magneto cooler, then runs out. This connection is a quick connect that the manual says to disconnect for winterization. I never do and run the pink stuff all the way thru to the tee.

That was the first thing I checked. All is well there.

The water being hot makes me feel like it's a leak ride with the seat off

This may sound dumb, but how do you do that? Remove the seat, straddle the engine...but how do you look for leaks, put it under power and steer at the same time? And my suspect is the water regulator, which is behind me.
 
It's not that bad I leave my trailer on the ramp go out looking for water while idling if I see nothing I pin the throttle and look down.

I know you are in GA also. Over by Augusta if I remember correctly. I am up on Lake Lanier. By the afternoon, the lake was running 3 ft chop just from all the boats! My son was jumping everything in site. Not sure tomorrow will be any better, so not so sure we'll be able to try it out.

I have a jet port on my dock, so at least I am not holding up anything at the launch ramp.

Just pull the seat and ride. You'll find your leak quick. The leak could be on one of the thru hull fittings and the water is getting hot from contact with the outside of the motor and exhaust. I see it all the time
 
Got back out to the lake this morning. Did a leak-ride. Found the leak! It is coming from a hose connection that is connected to the bottom of the engine on the starboard side off center from the PTO. It will shoot water up to the seat level, but seems to do it only when warm.

I need to examine the cooling circuit, but it looks like the engine low point drain.

Since it is way down there, I had to stop the ski to feel the connection. I could not feel any splits. You can barely see it and I will need to remove the seat support to do anything.

Should this show up if I put the ski on the hose?

What else?

- Dave
 
I would replace the entire hose could be a defect in the inner walls water will cut any thing
 
Thanks. The hoses are the clear 1/4 (I think). Well, they are kinda yellow now. I am concerned that it could be the actual fitting that is screwed into the block. Is that a common point of failure I should be worried about? It seems to me the hose end connection would fail way before that fitting. Also, it was winterized, that hose was full of the pink stuff and garage kept, so I don't think freezing was an issue.

If you or anyone have any hints about how to work in that space, I could surely use them.
 
Guys:
I need to bump this.

I find PVC braided hose that will carry pressure, but has a max temp range of 150F. Hell, it's 100F in The ATL today. Will the engine heated water ever get to 150F?

Then I find Silicone tubing with 500F rating, but a burst pressure of 30 psi. What pressure is this drain system under?

What tubing should I use for this drain line? It comes out the bottom of the engine and joins with a T. The same kind of tubing comes from the block and drains the cylinder water jackets. The 3rd outlet of the T drains to the exhaust.
 
It is leaking right where it connects to the elbow on the bottom of the engine. At least that is where the spray was coming from. It is so close to the PTO, I am hesitant to put my hand down there with the PTO spinning to pinpoint the source. You cannot see it.

I also have not gone down there and disconnected the tubing. It is attached with a zip tie. The ski is on its jet port right now. If I pull that hose off, I cannot get it to the ramp before it sinks. If I leave the hose on, water gets to the bilge, but it only takes about 5 minutes to get to the ramp and the leak will not fill the bilge in that time.

Tygon? That is a 130F tubing with 18psi pressure limit, right?
