Rage 14 Cooling System Question

[Estam]

Just purchased a 1995 Rage 14 and have a situation where the bilge pump runs when engine is running.

Knowing the raw water comes from the turbo jet am assuming there is a leak from the turbo jet to where ever it hooks up to the engine.

Can anyone help me to locate this hose or find a cooling system diagram showing the layout?

Many thanks for any help...

Shouldn't be using the tern TurboJet, mean Jet. and Raw water meaning water...
Rage is a Jet Boat and thought that maybe someone on here may have owned one and had experienced similar.
Not having any luck with that site either....

@Estam I assume you have a 115 OMC power head with a Turbojet. Can you open your engine hatch and watch the motor while it runs? Classic Whaler: Boston Whaler: Reference Here is some info I found on the cooling system.

May find this exploded parts diagram helpful... https://www.boats.net/catalog/omc/turbo-jet/115hp/115jeera

From the service manual in part 1 of video. Warm and Cold water directional flow.

Thanks Zipper, had the boat out today and and due to the heat of the engine shouldn't get much of an idea of the water temp. Buddy is going to loan me a laser thermometer so will check back with you Monday.
I found a rubber hose laying down under the carbs, about 1/4 inch in dia and couldn't see where it goes and wonder if you could help. One end is connected to a fitting next to the number 2 piston head (port side) and the other must go somewhere close to the carbs. I only say that due to the length and the way it naturally curls towards the carbs. I cant see a fitting easily that it could connect too.

A good close up picture can save a thousand words and help us help you.

Here are two pictures, both showing each end of the hose.
There are two arrows and the one hose end with the yellow tie is the end I trying to find a home for and just have it sitting there to show.
The other is bit harder to see but the fitting it connects too looks like it goes into the head, or close.
The overall length of the hose is long enough to anywhere around the carb area.
I hope this is enough to help identify it so I can find where it plugs into.
Many thanks for any help.

The wall thickness on that hose leads me to think it is a vent or air/vacuum hose, not a water hose. Unless you have seen water coming from the hose while running. Where does the other end connect?

 

[Estam]

I think your correct it is a vacuum hose. I think there is a slight oil residue coming from it, thinking it was connected to the carb.
I cannot see where it could be connected, somewhere I'm sure... : -)
Any suggestions please.

 

[Estam]

Looking closer it seems this fitting is in the area between the two heads.
Unable to see much due to being in a small area.
Any suggestions please.

Found a fitting just in behind the carb that screws into the block.
The hose connects to this perfectly.
Any suggestions what it does?

IDk, without seeing it myself or pics. Breather or vacuum.
