Atomic 4 - Water in Cylinders!!!
I strongly recommend you source out a shop manual if you''re planning to do the job yourself. That will answer all of the questions you''ll have on how to go about the job and tools required as well as bolt torque, patterns and the like. It will also keep you from getting into too much trouble. Doing this job yourself is a great idea, as it will give you some very good experience and knowledge about your motor, which may come in handy someday away from the dock!
