Hi,
i have a 1977 15hp johnson outboard that i have recently replaced the head gasket in and just last week the motor stalled on me so i did a compression test and found the top cylinder to be 60 psi and the bottom about 80psi. after the head gasket was replaced i had intial compression readings of 125 on both cylinders. after further investigation i found the head bolts had loosened. does anyone know how many foot pounds to tourque the head bolts on this particular motor is? do you think i should apply thread lock to the head bolts?
