I'm thinking about changing the old packing seal to a drip less. What do you guys recommend. Seems like a lot guys went to pss is that the way to go. For install I'm guessing I have to take the flange off the shaft. How hard are those to remove. I know you have to heat it but will propane or mapp gas work? Any info will be greatly appreciated.
PSS is what Vince at Skidim recommended and it's what I installed and I wouldn't change a thing about it.
Jet how bad was it getting the flange off the end of the shaft
I'm definitely interested in how this goes, I'm thinking about doing it to my Launch.
Couldn't tell you as I had my whole engine and trans out when I did the swap so I just pulled the prop off and slid the shaft in from above. It was super easy the way I did it.Quote:

This is going to be a fall or spring project. Just trying to arm myself with info. My packing is still good just figured when I pull it out for the winter I'll tackle it before I drop it back in. I haven't really used my supra all that much this year. Still have the original tank of gas from the spring in it and it's still 3/4 full.
Cusefan,
I went with the oj dripless on my 91 comp. Works fine and was cheaper. It's what was standard on my 12' response. Only caveat is be careful with the graphite lips when installing as they are fragile. The PSS looks pretty bullet proof and like a great system. I'm not sure what clearance you need for the PSS. My coupler had been on for 23 years and if I remember right just took PB Blaster sitting on it overnight and some scoring at the joint line and gently wedging a sharp putty knife into the joint with patience. I don't recall needing heat. I'm not sure which coupling is on your shaft. My shaft is 1" with a king nut and small key way, didn't have to buy any extra tools. My boat needs hours too, only on second tank for the season. Good luck!
I installed PSS on both of my Correct Crafts, and my Supra came with an OJ installed by the PO. Both work very well, but like others said, the ring that has to go on the shaft with the PSS may tolerate a scored shaft (the part that is inside of the coupler) better than the OJ. The PSS's graphite seal has more clearance around the shaft, and the stainless rotor that attaches to the shaft has rubber o-rings instead of (what I think is) more graphite. I'll never own another boat (for long) with a packing on the drive shaft, and I'll probably stick with the PSS when I do my next one.
As far as removing the coupler goes, there are a few tricks. Like NOWAKE said, backing the nut off inside of the coupling, then using the flange bolts to pull it back together working as a press is a good option. I made a copy of this tool to put in cutlass bearings and take apart shafts on 1" shaft boats:

I've never loved reacting that slide hammer force through the transmission, but it's what they say to do, and I've had a few boats apart with it now, with no problems..
The first boat that I did I had the engine and trans out of, so I pulled the shaft inboard. The second had a worn, loose fit here from running with a bad alignment on a rigid mounted motor (1970 CC Barracuda). I actually ended up replacing the entire shaft setup on both with an ARE shaft system from DIM (HIGHLY recommended if you ever replace a shaft, super easy to take apart again if you need to). My supra seems to have an original shaft and coupler with the OJ.
As usual, talk to Vince at Discount Inboard Marine, he'll be happy to share his experience if you buy the parts from them!
I have an excellent solution to your problem Ken. :lol:Quote:

Jetlink I bought a PSS for my 87 Supra Comp Ts6m, just wondering how did you manage to fed the water for cooling. Do you have pictures?
Pull it from after the impeller pump and before the tstat distribution housing. Slice a fitting between or if the tranny cooler is after the impeller pump there may be a fitting on it
It is tapped and pulling right after the raw water pump prior to the thermostat housing. I do not have any pictures of the setup handy and I will not see the boat again until late April. I ended up sourcing a fitting instead of using the one that came with the kit as I was pulling from a larger diameter hose than the kit intended.Quote:
