RE: need help for my rio 51
keep in mind when you regrease the cable most of the grease gets wiped off when you put it back in the stuffing box, if your boat is new it might take a few applications to get a good build up, also if your stuffing tube will allow down sleeve it on the motor side with another smaller tube just a few inches in maybe even 2 sleeves downsize as long as it does not bind on your cable, this is general info and might not apply to your boat, ive seen them but have not really worked on them.
