I own a Javelin boat and it has a 150 hp Johnson outboard......Coming out of the oil tank is bulb that is always stiff......but coming out of the front of the motor where all the hoses are is another bulb that has always been soft since i bought the boat new....what is this 2nd bulb for and is it suppose to be hard or remain soft......And does anyone know where I can buy a quality gearcase oil and other grease and oil for maintenance without having to go to my dealer? He knows hes a rip-off......Is synthetic ok or should i just stick with Johnson products?
