  • 200 HPDIs 2003 - Won't pee connected to flush out

    I have twin 200 HPDI's 2003.
    One engine won't pee when connected to the fresh water flush out.
    The other engine pees fine when connected to the same fresh water hose so I know there is enough water pressure.

    I must have a blockage? How do I clear it?
    I tried with an 18 inch piece of weed wacker line in both the pee hole and the raw water hose but it did not help.

    Thanks for the help

    Does the motor pee when the boat is in the water?

      Yes, pumps well from the water pump. Just the flush out is blocked it seems.

        There is no problem with the motor.

        No two motors of the same model are just alike.

          Sorry, I did not understand that reply. How do I unblock it so I can properly flush the engine after each use?

            Did it just stop peeing all of a sudden or was it normal and eventually stopped?

            If you can remove the hose (where you hook your garden hose to), I'd start there.

            Its kinda odd it pee's with the WP but not the flush fitting. Follow the hoses and where the water goes...

              Water form the pee hole is not the water that flushes the block.

              Now if you are thinking that the flush hose is blocked, run the motor in the water with the flush hose fitting disconnected. See if water flows out. If not, trace the hose to its fitting on the block. Remove the hose snd inspect first the fitting and then the hose.

                I know this will be confusing to you because one motor does and one does not, but here is what Yamaha says in their FAQ's

                "I don’t see water coming out of the overboard indicator when flushing. Is that a problem?
                The overboard indicator is for visual verification of water pressure under normal operation. If you are using the convenient flushing attachment feature without running the engine, it is not a problem. However, if you are running the engine while flushing using a flushing attachment like muffs, stop the engine if you do not see water coming out – the engine is not getting adequate water pressure for proper cooling. Correct the problem before continuing to avoid the possibility of serious engine damage.

                  Yes - It used to pee from the flush out just fine.

                    I could buy that explanation if it never worked. But it did. Now it doesn't so something had to have changed. I think there is some mud packed somewhere . Just clueless on how to get the system clean.

                      You can try some compressed air injected into the water while flushing to see if that would move things around

                        Follow the hoses. Remove the hoses and check the fittings. If the hoses are clogged clear them. If they can't be cleared replace them. If the fittings are clogged clear them. If they can't be cleared replace them.

                        This is not rocket science work. If I have water coming out of my spigot, but not out of my nozzle at the end of the garden hose when the hose is attached to the spigot, I am guess that the problem is with the hose or the nozzle.

                        We are only talking about a few hoses. If the tell tale pees when the motor is running in the water then we know that it is not the tell tale hoses from the block. If the garden flush hose emits water when the motor is running in the water we know that it is not the garden hose flush tube.

                        More time needs to be spent at the motor and less at the key board.

                          How do you know how much time I spend on each? The boat is in the water and I am not a mechanic so figured I would ask on this forum. no one said it was rocket science but the hoses are not easy to follow and I don't want to break anything. There used to be a guy named rodbolt who at least through some of his sarcasm added real value. None of your answers have done that. Thanks anyway.

                            Actually, he did explain quite a lot - in terms of just thinking about this logically and the way that water flows through. He may not have given you the actual "answer", but he offered some advice and guidance on being able to figure it out for yourself.
                            Which, quite honestly, is more valuable. Note that he used a "smilie"... I think Boscoe (at least the way that I read it) was really just trying to say that sometimes you simply need to get your head in there and look/poke around. Often times, you can answer your question if you take some time to think about it or give it a real good look. Heck, I've been guilty of looking for the answer somewhere else, too - when I really should have just taken more time to think about it. Don't worry - you won't break anything - just use common sense and it'll be fine.

                            Is one engine tilted more/less than the other? That can sometimes cause this "issue" (which really is a non-issue), too.

                            FYI... Boscoe answers A LOT of questions - he even gets a few of them right from time to time! (note the "wink"... it's sarcasm... he gets them right A LOT!).

                              You are welcome.

                              Like so many you want a silver bullet thrown your way.

                              May I make one final suggestion. That you take your boat and motors to a Yamaha mechanic who can trouble shoot and perform a fix for you.

                              I try to help those that I can. Some can follow directions and are willing to get their hands dirty. For those that can't, there are trained Yamaha mechanics available.

                              There is no shame in not being able to fix ones motor.
