Mokai Jet Bilge Pump!

[AVAdventure]

The Mokai Jet Kayak has unused ports in the jet drive.

Could the return port be used as a Bilge Pump?

Seems to me that it would be difficult to suck up water at 1 bar with a "vacuum" operating at the exit pressure of the jet unit at 106lbs!

The Mercury Sportjet has a Venturi bilge pump in the tail pipe in the pressure zone. Works reasonably well. No reason it wouldn't work for this pump as well

Any Pictures of the unit? I have seen similar tubing on other jet ski type applications!
I talked with Mokai and the port as designed is used to provide a Return from the built in supply!
With 1/8" tubing it will circulate water without a added pump from the supply to the return!
Their testing showed that the return port never dropped below atmospheric pressure! :idea:
Would that not make it difficult to Suck Bilge Water???
Thank you for the response!:!:

Waste of money!

This port was meant to be a return line from the other supply line!

Using this as a suction port is possible but not worth the effort!

They return water back to the pump rather than to waste through the exhaust?

You could always add a venturi into the tail housing for your purpose

Pump Not! This doesn't Suck!

True, in this design it can work without a pump for cooling!
Others are trying the return as a suction port without much success.
Not worth the effort to add a venturi and with the limited HP driving the jet with a "lawn Mower" engine. Would cost more in speed than it is worth!
Why I use a Spray Skirt in heavy weather!
Thanks!!!
