Breather lines?

[LiterateStylish]

I just bought a 1995 Seadoo GTS. There is a line that's not connected to anything. Guy told me it's a "breather line". Is that true?

Who knows. Post a pic.

Chances are... it's the vent for the battery. They fall off, and people don't know what they were for.

Hi Dr Honda!

Here's the start of the line...

And here's where it ends...

And here's a picture of the battery.

 

[Dr Honda]

is it hooked to anything on top of the engine?

I see a few other issues... but if it's not hooked to the engine... that was the hose for the battery.

Looks like it's hooked to the engine to me.

Look where my red arrow is, and then follow the line down to the right of the picture. It hooks in to the white object right next to the grey object.

You can't tell from the picture. It's a bad angle. To me... it looks like it was a loose hose, flopped over the engine. I try not to assume things. that's why I asked if it was actually hooked to the head. Telling me "It looks like it", isn't the answer I was looking for.

BUT... on some of the 657 engines... they take the "Pee-Hole" hose from that corner of the head. If that's what it is... then it should be hooked to the nipple by the transom eye, and on some... they run 2 hoses to the pee-hole.

But the other problems I saw were... the 90 degree elbows on the bailing hoses should be supported higher in the transom. With them laying in the bottom of the hull... water will come into the bilge when you are sitting in the water.

Also... there isn't a vent hooked to the battery, that I can see... and since it's a wet battery... it will spill acid into the hull while you are riding.

Sorry about that Dr. Honda. I'm not mechanically inclined so I'm trying to do my best. I made a video for you to look at, so maybe that will help you diagnose the problem. Here it is:

Thanks for the information. Is there any way you can put this into layman's terms for me? Like what exactly I should do to rectify each situation?

Ah.... Perfect.

That was the hose for the "Pee-Hole", or "Tell Tale". While the engine is running... it's the way you can tell if there is water pumping threw the engine. (so you don't burn up the engine)

On the back of the ski, you have a place to hook a rope. Directly under it, there is a small hole. That hole should have a fitting that the loose hose would hook to. That hole is known as the "Pee-hole"... and as before, when the engine is running, and water is pumping, you will have a stream of water coming from it.

So... when the engine is running, and that hose is hanging in the hull... you will be pumping water into the ski.


The bailers:

This system removes water from inside the hull. It woks by drawing a vacuum on 2 hoses, and they are hooked to those 2 black plastic boxes that are strapped to the bottom of the hull. (either side of the drive shaft) The vacuum is made by water being pumped past 2 tubes in the jet pump. (You can see them hanging down of you look into the nozzle on the rear of the ski) Since the vacuum source is in the pump... you need a way to keep water from flowing it. That is a simple thing to do... just make the hoses higher than the water line.

If you look at the hoses... you will see a plastic 90 degree elbow. Those should zip-tie up to a high point in the rear of the ski.

Your battery vent is under the red circle. The nipple for a hose is pointing down. Somewhere in you hull... there should be a hose going from that battery nipple, to the rear of the hull.

Ohhh. Gotchya! Thanks for the info. Does the battery vent hose usually lead to outside of the jet ski?

BTW, I am getting water in the hull. Do you think thats from the bailer issue you were telling me about above (earlier in the thread)?

Yes. On the 95 GTS... in the rear of the ski... there should be a black plastic vent box. (Hooked to the vents in the transom) Some where near the top of it... there should be a fitting that is used as the battery vent. SO... if any acid gets out... it will get washed out the rear vent. If you take a picture of inside the bilge, showing the transom... I'll look to see if the fitting is there.

BTW, I am getting water in the hull. Do you think thats from the bailer issue you were telling me about above (earlier in the thread)?

You will always have a little water in the hull... but yes, your bailing hoses will be letting water flow in, any time the engine isn't running.

You may have a pinhole leak in the tuned pipe, it has four welded plugs that rot internally, and at first spring a small pinhole leak.
"flooded" lead Acid batteries require a vent, SLA or sealed lead acid batteries do not.

What is the tuned pipe? Where can I find it?

Dr. Honda thanks a bunch for the info. I'll look for what youre talking about and post a picture!
