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!
