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

Horsepower of engine? :-?

20 hp...sorry about that. Compression was checked at 120 for top and 125 for bottom.

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.

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....
