Assuming the spines, a lack of grease will cause the coupler to fail. If it is aligned and greased, then something is flexing. Either an engine mount or the transom. |

Try standing on the outdrive, just above the prop, and jump on it some. Look for any flex in the transom. I don't think there is a possibility of teh transom being soft at last survey moisture reading was 5 or 6%. The surveyor said it was one of the driest boats he ever checked. He said a brand new boat will hit 6 on his meter. The boat has only been in the water 30 times since then and only over night once. The only thing I can't tell the condition of is the rubber and steel bushings that are installed in the bell housing. When I pry on that with a bar it is thight as can be. Those were replaced when I replaced teh motor 2 years ago. Still searching.... |
OK, long shot, but I seem to recall reading something about HP couplers requiring somewhat of a different process over stock when putting the motors in. Wish I could remember the thread. That is the only thing I haven't seen mentioned already. Hope that helps, I'm out of suggestions.

But i could be wrong. |
im having the exact same problem! i just blew the second coupler in 30 mins of boating! my motor mounts a offshore as well and the strigners are fine but we did find the top gears in the XR drive were worn and blue, my drive is currently being looked at by a mercury tech as it is still under warranty, my mechanic doesnt understand why this is happening either as alignment is perfect, every one is saying alignment and everything seems fine in my boat, we even tested the stringer by lifting on the motor while it was still bolted to the mounts and it pretty much lifted the boat off the trailer so its safe to say the stringers are fine! dont know whats going on either
|
the drive/input shaft have some runnout?? a little wobble would do the same thing as a bad alignment...
|
what do you mean by runout??
|
very slight bend in the shaft
