    . The one thing that stuck out was the pressure of the discharge water came out. Good lord it was like a full bore garden hose!!

    That water discharge is all the cooling water, not just a telltail stream to tell you there is water circulating like most newer motors have. There is no thermostat so it pumps like that all the time. This is on all 1955-1958 Johnsons/Evinrudes from 5-1/5 to 35 HP, except the 1958 Lark and Super Sea Horse 35s that have thermostats.

    Note the high speed carb jet is very touchy on your model – a half a number difference on the dial can make it run lousy – and like the others said – set this at max throttle on a boat.
