Uncle gave me a 1970 Johnson Seahorse. Got the motor starting and running very good for sitting over 15 years. Barrel test satisfied and I mounted it on a jon boat to water test...whopping 6.9 mph. I was hoping for a little more speed(Should I be expecting more speed?) Getting a new skiff and the 20 hp Yamaha is being traded up, so I am stuck with this motor to power my river/duck boat. Any suggestions would be helpful. Getting it running was step 1. Thanks
Are you sure both cylinders are firing? Those 20 ci engines will run on one, but no power. If both plugs are firing then the carb is the next place I would look. Frank_S
23 mph today. Checked cylinders last night. going to keep running and see if it stays consistant. Thanks
bummer doesnt that foot have a two piece housing? - theyll be screws in the bottom on both sides if so you should be able to get a kit fairly cheaply (20 - 30 bux and theyre pretty straighforward to do....
