My 82 H27 had a very shallow bilge which had a pump that is only on when the breaker is on, it has no float switch. Is there a reason Hunter did this rather then putting a float in? I am debating locating a float a bit higher up maybe in one of the corners of the engine compartment so that if there is a problem when the boat is at the dock and I am not there it will TRY to pump out some water if it gets high enough...does this make sense to any one or am I wasting my time?
