On the CS-36T the tank runs port to starboard behind the engine and under the cockpit. Because of this the engine must be removed to replace the tank. Removing the gear box and using a block and tackle, AKA main sheet, in the companionway made this an easy task. I simply set the engine in the galley on boat yard blocs while waiting for the new tank.


This photo shows the new tank ready to go get buttered up and slid into place. Even with the engine out this was still a tight fit.
