groco eb head

[seasession]

The groco eb style head on my 32 sportfish refuses to work properly even after replacing the piping to the holding tank, rebuilding the pump, and doing every other thing I can think of to solve the problem. The head pump runs but will not evacuate any more than some liquid with what seems to me to be to long of a run time.Before I replace the head and every other part not attached to the boat does anyone with have any suggestions.

These heads will last a lifetime, they just have to be rebuilt properly. First make shure the check ball is in correctly. Secondly the keyways on the shaft wear, always replace the shaft and make shure the arms are tight. The rest of the kit is straight forward. Dave
