I have what I believe is a 1954 Johnson Sea Horse "5 1/2" HP, Model CD-11. It has not run for at least 18 years. It ran good the last time it was out. I have two questions that I could use some help with. First, before I put it back to work, I would like to replace the water pump. So where can I find a new water pump. Secondly, is it possible to convert the fuel tank/system from a two line, pressure type tank/system to a system with an engine mounted single line, fuel pump system. I would like to take advantage of the new type fuel tanks. If this is possible, what are the required parts and procedure.
