My 1975 Johnson 25 ran decent for a few test runs late last year. This is an old hard used salt water motor that was left to rot and I gave it a new home. This year it will start and run smooth for about 20-30 seconds and then is starts to bog. I pull the choke lever and it struggles but then...
I am restoring a Johnson 25RL75B tiller outboard. It's a 1975. While replacing the thermostat I found a rubber plug in one of the water passages. It is not shown in the parts schematic. Is this required? Has anyone ever seen this?
