  • water pump

    My 150 4 stroke water pump goes out regurarly been replaced 3 times in the past year by two different shops its not peeing now and overheating what is the problem

    could be the way you run it or where you run it..
    is there a lot of sand/dirt, sea weed, or trash in water?
    do you run it in real shallow water?
    do you ever start it up when up out of the water?
    do you replace the impeller only or do a kit?

    what has the ones you pulled out look like( problems found)?

    No magic crystal balls for us to look into, so you will have to give more info

          Not sure the hours
          silty muddy water,
          jet drive , sometime I pump some sand too.

          Probably closer to 200
          Working on getting a tack & hour meter installed

          Pays to check it.
          I got lucky.

                  Oh OK....Thanks for the good pics......helps to see the parts and how they wear...
                  I will probably wait till 200+ hrs as long as it keeps a good stream going.

                    Never hurts to drop lower and check things out every year.
                    Allows all the bolts and shafts to be cleaned up and lubed.
                    May keep you from writing about not being able to drop lower unit some time in the future

                      Good point!!! I will do that... any recommendations for lubricating the threads.. like anti sieze or marine grease?

                        Anti-seize on the bolts too.

                            Stay with what Yamaha recommends in service manual

                            Stay way away from anti seize that has any copper in it,
                            aluminum and copper do not get along

                              Yea
                              I pump some sand.
                              pump glacier silt & sandy water 99% of the time.
                              Sometimes gravel too.
                              Old jet drive foot. Not my damage.
                              I replaced the foot, got it welded & semi straightened up for a spare.

                              Gotta be Yamaha tough to run rivers in Alaska
