I have a 1957 fd11k 18hp Seahorse Johnson motor that last ran in 2004. At that time it needed a tune-up and was taken off the boat and put in a boathouse where it sat until about 1 month ago. The motor was not fogged prior to sitting for a few Wisconsin winters. I tried to pull the motor through and it does not budge. Tried PB Blaster in the cylinders, sprayed in after removing the plugs. Have added more over the past few weeks, still does not budge. Looking for suggestions on how to address this. I have ordered a Seloc manual and will tear down if necessary, but do not want to go that route if it is not needed. I am looking for any help, pointers, suggestions......
By needing a tune-up it would start and run but ran poorly. Coils and points were last replaced in the early 90's. Not sure if the carb has ever been rebuilt, but at a minimum I suspect it needs a good cleaning. I had planned to check the coils, points, carb, etc before finding out it was seized. Is this thing worth the effort, or is it time to find something else?
