Quick towing question

[SabotageR1]

How does water end up in your engine when towing a PWC too fast? The only two inlets i see are the exhuast and the water hose line. Which one of these allow the water into the engine when towing too fast?

exhaust inlet, without the engine running there is no exhaust pressure to keep water out of the engine.

Thanks, I appreciate the response.

It's the cooling input line from the pickup inside the pump. When your engine is running, it pumps water through your cooling system of the exhaust manifold and pipe. When you tow too fast, it has the same effect but since there is no exhaust pressure to blow it out the exhaust it fills up the entire system and then backfills into the engine through the exhaust. You can add a valve on this line and then tow as fast as you want.

Thank you, I have an older 1999 GTI and a 2016 GTI, I'm assuming both ski's share the same principle on how to stop the engine from flooding, correct?

The owners manual shows you how to clamp off that line also

From what I've seen, the older manuals do, the "newer" manuals do not. They just say don't tow over 15 (and even 5) mph.
For example a manual for an '08 GTI shows how/where to clamp, 2011 GTI manuals do not.

I have these to clamp the exhaust hose:
