I just bought a used 1997 gts and replaced all the hoses. The flush "t" is on the outlet side of the head, the manual shows it the same way and having to clamp the outlet hose to backwash the system. Why? Why is the the "t" not on the inlet side on this model?
I know on the boats, well on mine, use the flush spigot underneath the hatch, and not the swim step, because it causes to much pressure for motor to push all that water, maybe similar to ski?
