Question: I developed a vibration in the driveline and there seems to be a “slip” similar to a slipping clutch on a car. I took the cover off to check the driveshaft, and sure ‘nuff, it was missing a bolt on the flange to the v-drive, and the other three were backing out. So it appears that I found the source. Now for the slipping. All keyways are good from the prop to the motor. Is there a chance the driveshaft may be slipping between the ends where it telescopes?
thanks,

Unless you have a trans, there's nothing to slip unless the prop is cavitating. Maybe it was the vibration that gave you a slipping sensation!?.

that's exactly what i was thinking, but just wanted to be sure before i put it all back together. I'll double check everything, and put it all back and let you know the results.
Have a good 4rth and Thanks for the replies!!!!

Randy make sure you use at least Grade 8 bolts on the driveline with lockwashers as well and I always locktite them too for insurance. That's one thing that can really ruin your weekend if it comes apart.
yea, i picked up pome stainless bolts today. This time, I'm gonna use longer bolts so I can back them up with nuts on the back side of the flange. I got the ruler out and checked the distance, and there's plenty of room.
Stainless bolts are not very strong. You may want to do as Rexone said and use #8s.

Randy, use ONLY the very best grade 8 fasteners, through Rex or the vendor of your choice,(I get mine through ARP). I not only Loc-Tite them in I also saftey wire them and they are ABSOLUTLY ONLY USED ONCE then dicarded.
Fasteners only have a ONE USE life cycle, espesially when in the EXTREMLY HARSH application such as HP drive operations. In my race program this is the ONLY answer, it's gospel. Anything less is simply UNACCEPTABLE.

Take the stainless back and trade them for grade 8's, and if you're going to use nuts on the back side, get "Nylok" JAM nuts!..
