  • Fresh water holding tank

    Does anyone know how to drain the fresh water holding tank on a 1987 Bayliner Trophy?

    Well not specifically your boat, but on most boats the fresh water tank is pumped out using the hand or electric water pump through the sink/head ETC.

    If you want to get the old water out and put in fresh because it is getting a little yucky, pump it out and then use some bleach and fresh water to clean it out, rinse/pump out repeat.
    A couple of times should remove the slimey stuff and smell if there was any.
    home is where we drop anchor

      Thanks Admiral. I was hoping that there was a way for a quick drain or an opening or some other way. That will take a lot of pumping with the manual faucet.
