    You can run it without a prop but be careful as it will tend to be easily over revved and that would be bad…very bad…. as for cooling yes without a prop just connect the hose or 12 volt bilge pump to force water thu the opening, OR you can use the bilge pump and split the output to each cylinder.flow I think is from the bottom of the cylinder to that top. Just make 2 dummy copper water lines, and connect them with rubber hoses to the bilge pump…AGAIN watch for over revving…
