The hoses that attach to the pee hole are inside the ski. The flush port hose runs next to the water box “muffler” and it’s just a little T that the pee hole uses in the hose connections. I suspect the little “like 1/4 hose” that is in the line is clogged between flush and pee hole route. It probably does not matter but just need to follow the lines and remove the line codes to the flush port and work backwards. It also takes tons of pressure for flushing to come out the pee hole since the water box / engine gets most of the water pressure.
I cannot thank you enough for your response. Am I correct in assuming that when the skis are in the water, the water is clearly coming out of the Pee hole, and that is because the pressure forcing the water out the pee hole is much greater than the pressure created by my garden hose? Also in your response above you say on the second to last line "remove the line codes". What did you mean to say? Finally, since I am just a dumb lawyer, who actually does change the plugs, coils and oil on both our Honda Aquatrax's by myself, since I have a shop manual, would I look up under "muffler" or "water box", or "flush port hose" to see where the little 1/4" hose is that you are referring to? Lastly, is it easy for me to see the 1/4" hose that you are referring to with a light once I remove the seats and the apparatus that holds the fire extinguisher? Is the 1/4" hose made of black rubber or metal and how big do you think it is? Thank you so much, again, because no Honda dealer will work on both of our 2005 Honda Non Turbo Aquatrax jet skis any longer, and yet they are still running beautifully.
