Can i tow jet boat ?

Hey all. I have a RIB with a Mercury 120 XR2 sport jet. Can I tow it after my big boat? I know that some boats require you to shut off the cooling water flow and prevent the engine from spinning.

You will want to clamp off the water line from the jet pump intake or add a shut off valve to it. I just have a set of hose clamps in my boat for this situation.

So I did on my jet ski, but found no info about it on the specific Mercury sportjet. in the instruction manual it says that you should flush the engine via this hose after driving in salt water, this is done with the engine turned off. If it can be flushed with the engine switched off, maybe it should be possible to tow it?

Interesting....perhaps they build in some sort of back flow valve? The only risk you have with clamping it off....is forgetting to remove the clamp!

It is a fairly coarse and stiff hose, and difficult to reach. So I can not squeeze it. then there is a lack of space to mount a valve, which is why I am looking for someone who actually knows what applies to this engine.
