Bought it used at end of last season, everything has been good for about 25 hours of use. Then this weekend we were putting along at 1000rpm and felt a “clunk”, initially thinking we hit a log in the river. After the clunk we could still idle in forward and reverse, but if we tried to go over 1000rpm the boat would start shaking in forward, and in reverse we could hear some clunking. After pulling the boat out the prop looked fine, but noticed I could move it in and out, the whole prop shaft. From the inside at the v drive, we could see the shaft move away from the coupler about 3/8”. Was able to tighten the nylon nut on the v drive end and the in/out movement stopped. I found a similar issue on a mastercraft forum, but that guy had the nylon nut come completely off. Anyone else had a similar issue? Anyone know where I can get that nylon nut? It’s different than the one on the other end by the prop. Thanks in advance for any help, I’ll dig around and see if I can do better at uploading the pics.
