I just bought motor it is 1990, 90 hp johnson seahorse.model # J90MLCTE.Had just replaced bearings and seals on propeller shaft. I also had pressure check on rest of motor.Am having some water coming out of lower unit where the four bolts are to upper unit and also there are two plates on each side of lower unit with four bolts in each that leak some water. Is this normal or do I need to fine out what is wrong. Motor runs great and have had it in water.
