anyone know what a johnson 88spl should be getting for water pressure? am getting about 15.. going to lower the motor to elimitate that possibility that it is mounted too high..dealer supposedly put a new lower unit on this motor when i bought imo a new impeller should have been done at same time, but from my experience with them i highly doubt it..hoping can get the rest of the month of it as is , then season over anyways - didn't know what registered prior to that as just installed a water pressure gauge to help when making jackplate adjustments
