Looks like lift mufflers, if so the engine must be running regardless of exhaust geometry (even if engine dry riser is the highest point in the system) or you need to crack open a drain on the muffler which is likely not realistic. I would set it up with the dockside water and let the engine run and flatten the hose, won’t hurt anything at idle since the impeller stays wet. Then pop a zinc and taste what you have sitting in your aftercooler and/or heat-ex and go from there as to seacock open, closed, etc..
