Is there a better system than Fountains factory system?
thanks

there are a few ways to make a change. depends on how fancy you like to get. the factory system isnt all that pretty but it is functional in the sense that they keep the shut off valve very close to the transom, which is best in an emergency situation..
you can probably change it to a more finished look by changing the valve from a rotary close to a 1/4 turn or ball valve. and if you install strainers you can plumb the flush directly into the strainer. use an aero quip type quick disconnect for the actual flush connection, and you should end up with a very functional trick looking install.

good luck.
