shaft threading on reverse rotation

Exactly and I commented on it when I installed the ARE in my Tique. A steep short taper needs more "pull" to seat it in. I also commented that I also lapped the coupling taper to the shaft. Yup, even CNC machining isn't always the greatest! The taper needed the lapping.

Hey guys update! Sorry I've been away for A bit. I would have loved to post a pic and honestly didn't know how.
I did need to remove #8 Gary thanks for the exploded view. There was such little clearance that I was struggling getting to the nut. And I believe it was over tightened. I just wanted to know the thread pattern because I couldn't move it either way. After the nut came off the job went flawlessly. Thanks to a "heat/freeze" trick my skidim guy told me! Back on the water and no drips visible from the new OJ dripless. Thanks for all the input and patience.

PICTURES!!!!

From what you are describing, it sounds like you need to remove the nut for a dual taper shaft that secures the coupler to the shaft. In the A.R.E. dual taper system this is a standard right-handed nut (I can't speak for other brands). Depending on your set-up, there may not be much room between trans coupling and the shaft coupling to get a wrench in between. I don't have the special tool to hold the coupler when removing the nut so I usually use a long Allen wrench through one of the coupling holes to hold it in place.
As mentioned earlier, post a picture so we can verify what you're talking about.

Still doesn't add up - Why would you need to remove the transmission flange to slip the dripless seal over the prop shaft? is there not enough room? If so, maybe you can just jack the engine/ trans up (not very hard).

Even if it is a dual taper shaft or not why would you have to take it off just to change the shaft packing??? Like Tim says it's always best to post a picture.I kinda think he's talking the flange on the trans side,maybe wants to change the trans seal?

Sorry dont know what its called. Right where the flange from the trans and the flage from the shaft meet theres a nut on the shaft. Called oj props standard. Thanks!

Working on my tique shaft seal. Is the nut on the coupler side of the shaft reverse threads? I can't for anything get the nut off on trans side. Am i missing something? Any tips? Thanks!
