Bob Paul, How long is it safe to run a 50 hp Johnson hooked to a water hose? Will the pressure from the water damage any seals or the impeler? What is the best grease to use when greasing the stearing tube on the motor? Also when my motor sits overnight, I have to choke it to death and it takes forever to run without giving it gas. After it runs for a while it is real easy to start and runs fine. Is there anything I can do to help the motor start better after sitting overnight. Plugs are fine. New gas filter. The same with new gas or old gas. Is this a trait with the 50 hp Johnson?
