    Siphon tube? leave as is or cut it back?

    i am thinking if cutting the siphon tube in the exit nozzle would help with rpms and reduce cavitation. to me it is a useless item especially with a bildge pump in the ski.
    even with it cut back it is still a working feature.
    it also is a blockage in the pump.
    i had a GPR 2003 that i trimmed it all the way back. after i get my new liner and prop back i can do some back to back testing to see if there would be a benefit to not having it in there.

    If you cut the tube off it will try to push water backup the tube!!!!!!!!!!!! If you cut it you must plug it up!!!!!!!!!!!!!

    I just did this today on this nozzle and in the past on others...
    I didn`t clean the plug off flush and kept it removable just in case the stock bilge ever gets hooked back up...

    i guess that could happen. that is why there is a check valve inside the hull to prevent water flowing into the ski.
    try blowing on the hose going into the hull. you will see that it flows only one way.

    I have seen the check valves leak and let water flow back into hull this is why I plut the hose!

    I say leave it alone for peace of mind. It's too simple to fail.

    it creates a vacuum to suck out any fluid that is in the engine compartment.
