Show O equipped with a water 310 ( pump punip ) to keep it cool , plunger pump ; it ( wouldn't wouldnt ) ( work -work work ) because the ( sand saiid ) in the river would get around this pump and clog it up . As to cooling system on the big boat , they finally discovered a way to submerge some pipes on the outside of the boat so the ( water Nvater ) from the river ( would -would would ) ( keep heep ) these pipes cool , circulate the water on the ( inside insidd ) of the pipes through the motor , cool the motor , and back through these pipes again ; they found that the most successful way of cooling . Used the river water for that purpose ; dip it up and let it settle , then put it in the motor , so the sand ( wouldn't wouldnt ) cut the pump out ; used the same water over and over again . First tried pumping it out of the river , but it ( wasn't wasnt 'Wasn't Wasnt ) satisfactory because of the mud and stuff in the river , the sand . After the big boat was launched , his brother , Clarence Baldwin , had charge of the operation of the boat . He operated the big boat the first trip . ( "Witness Witness Witness ) had made a few trips down the river ( be- be ) fore that , so they let him go ahead with the small Evinrude boat , to help locate the deepest water . That is the way they got by ( without Ndthout ) quite so much trouble . The first trip got stuck ( and aud ) ( didn't didnt ) even have any anchor with them ; in case they broke a chain or anything to hold their boat from drifting away from where they wanted it to go ; ( didn't didnt ) have any steel cable with them ; had some inch Manila line , |
