My friend bought a 1972 Johnson 25hp sea horse. It ran great the first time we had it out.<br />Then yesterday:<br />It wouldn't go in foward<br />It would go in reverse<br />then it seized in neutral, won't go out of gear.<br />The prop is frozen.<br />The flywheel is frozen.<br />What may have happened?<br />Thank You<br />Otherwise when the engine did run we had fun and it ran good, except at full throttle, which it would bog down. We changed to a new fuel line and that worked. <br />The fuel mixture is 50:1 if I am correct?
