My water pressure at wot on my 1994 merc 60 is aroung 12 lbs. wot =5500rpm. At idle it id around 3lbs. Is this ok? Anything I need to be careful of when changing the impeller on this motor? What would cause the water to pulse at idle instead of a steady stream. Cant really see it pulse but can hear it on the water.
Thanks Kenny
