I read the recent post regarding removal of a "25" hatch.My hatch wont slide all the way forward or to the rear.Do the slides need to be removed to get the hatch off? Also,how do people install a bilge pump in a 22? There is only a hand pump access hole right in the middle of the cabin sole.Not a great place for a hose.I was thinking about using a "T" coupler in the sink drain hose for the outflow of the pump,that is,if I get the first part of the question solved. Thanks,Lloyd
