2003 Prostar 190... 1:1 transmission and 5,7 RTP-1, it has 1 1/8" shaft and packing was leaking. So I took the usual route and ordered 3/16" graphite seal from Skidim. Started to replace when I realized that old rope seemed clearly larger than the new 3/16". Installed it anyway... fitted 4 rings without any trouble. The rings seemed definitely spacious if not even loose inside the nut.

Tightened the package and went for a test drive. No leaks. It seemed to work ok. Some really minor drips when running, even loosened the nut a little. Gets warm but not really hot.

So my question is: How tight should the rope be when fitted to the nut, should I order 1/4" packing seal instead... can I really have 1 1/8" shaft that would take 1/4" seal?

on my 81 powerslot the prop shaft is 1 1/8th" and uses a 3/16" packing. your 1:1 should be 1" and use a 1/4" packing. I'd measure again??

I think 1redTA has it nailed - I believe the 1:1 boats all used a 1" shaft, and need 1/4" packing.

But, if it's buttoned up and not leaking, I'd probably let it go.

Per OJ in some other thread, since 2003 all have 1 1/8" shafts, also 1:1. I also measured it a few times, so shaft is surely 1 1/8".

As well as the shaft size, the packing gland will disctate the size that it will accommodate. If the current packing is working, I'd leave well enough alone. The graphite packing will take care of itself. You need minimal drip but there should be some drip invloved. I used to swear by no drip until I read otherwise from a convincing bit of information.

Size of prop shaft packing replacement on 04 PS197 TT. Does anyone know? Tired of waiting to here back from dealer for info and where to find if dealer does not have in stock.
