  • Flushing a 1974 Johnson 25

    I've been flushing the motor after every trip using a large plastic bucket
    filled with fresh water. I'll run it for a minute or so and then dump the water
    refill and repeat this time disconnecting the fuel line to starve the motor of gas.A buddy of mine told me that this was not a great method and that I should get a flush kit. I can't seem to find one for that particular motor.
    It has one intake under the cavitation plate. Does anyone know what I need
    and maybe point me in the right direction. Can I continue flushing with the
    bucket? This motor has been well maintained since 1974 and I would like to continue to do so.Help a novice out.

    you are doing it correctly for your motor. run it until the tstats open. then dump and do it again. a garbage can works real well. keep the water hose running during the process, as the exhaust blow more water out than you think.
