We have an antique Johnson Seahorse 5.5 hp outboard. We think it is a 1957. We have had it running this summer and it has trouble idling. It starts and runs for a minute but does not idle. We replaced one of the pistons and cleaned the carburetor. We think that it still needs some more carburetor work. We are asking $200 or best offer.

The following youtube URL shows the motor running earlier this summer:
