'90 Gulfstream. Im trying to replace the 4 thru hulls that are below the waterline. starboard side macerator pump thru hull is cake. starboard side fish box thru hull is giving me problems. the hose from the thru hull here is very short and hardly bends at all. i got the hose clamp off and may be able to break the thru hull off but i cannot reach the fitting at the bottom of the fish box to unscrew the hose from it to replace the hose. anyone ever done this? also, on the port side, the below waterline thru hull that the sink drains out of. OH MY GOD HOW do you reach this unless you have 6 foot arms????? its WAY down there. Any tips appreciated.
