02 Waverunner 1200 xlt

anyone have a diagram of rear compartment
And hoses connections?
Just bought this and runs awesome
55-57 mph 140 hours
Anyways , while sitting at the dock it started filling with water
I found the Venturi line from the impeller just sitting
Open in the rear compartment.
There is a open hose clamp on the end of it but I canít figure out where it is supposed to go.
Is this just a vent suction line OR is it a bilge siphon line? If so, is there a check valve supposed to be in line and where does it connect?
Any help or diagrams appreciated

Hi Kt, welcome aboard.
The factory bilge line is a siphon. when the ski is running the pump creates the venture efect to siphon. If you follow the bilge line up from the grate at the right rear of the motor it comes up to a check valve. Then out of the valve at 90* and into the back compartment and over to the left rear and exits through the transom to the a hose on the outside that goes out to the end of the pump.

Where it goes through the transom inside. it is the upper of the 2 lines on the left side. The lower line is cooling water in to the motor.

This pic is from the GPr manual. but xlt is an extended GPr. Basically. You'll probably have to remove a couple of the large exhaust hoses to get down to the transom to reattach the line. Not sure though as I'm lot familiar with the inside back of the xlt as it's a bit different from the gpr as far as the exhaust goes.

Hope this helps,
Dave

Kt, no problem, happy to help. Was there once too.
You need to follow up from your bildge pick grate up to the connector that's 90*. That 90* connections is the check valve. It should be high up. almost at the bottom of the seat. Typically the bildge grate is under the motor coupler just behind the motor.

Is the water coming out of the disconnected hose? Or are you looking for a low fitting that the water is coming in through?
Is the ski up out of the water and drained? If so can you post a pic of the back compartment and motor bay? Then maybe I can give you more direct answers and point you in the right direction.
