I have a 60HP (ELPT) Merc Outboard that just started squealing when in idle or low speed. I know when I did my first 100 hour maintenance, I skipped that part about lubricating the splines driveshaft because I thought I had to drop the lower unit to do that. Which honestly, I still do not know what they are talking about (I do not have the service manual). I read all over online and from my understanding I can just spray some teflon up towards the top of the driveshaft. I only have 150 hours on it now.
Has anyone had this issue and how did you fix it? Thanks
Well I ended up fixing it by putting some 2-4-C Grease on the splines of the prop. Which is weird because according to the maintenance manual I should not need to do that for another 50 hours. Just FYI for anyone else that may run across this issue.

Unfortunately my squealing noise came back. Looks like I will be taking it in. I think being without my boat is going to be worst then being without my truck - haha. Well at least I can get some pond fishing in this year. I will report back with hopefully a fix.
I am going to spray some belt dressing on there just in case. Thanks for helping.
I did go speak with the mech and he is of the mindset that it will work itself out. Kind of seemed like he knew about this one, but, wasn't offering to much free information, which is understandable.
I got this below from a thread that is pretty much speaking about the same issue I have.
"I have a newer 4 stroke Mercury that I got last fall. My engine squealed at idle and low rpms and then it would go away and then sometimes it would come back. I did an internet search and found some info on the Whaler website. It sounds like it might be the drive shaft rubbing. It is a high pitched squeal? Well what worked for me and other people is trim the engine all the way up and turn it all the way to the right or left. If you look up you can see the drive shaft. Spray some lubricant like Fluidfilm up inside there. Use the little red straw and spray away. The sound should go away. It worked for me but then it came back and I did this half a dozen times or so. By the end of last season the noise was gone. This year no more sound and no more spraying required. If you search the internet you'll see that this squealing has also been an issue for some Yamaha engines as well. Good Luck!"
So, for now I am going to see what happens and just spray the WD40 Silicon up the driveshaft to the rubber "boot".
If you ever see someone waving there hands out there on the lake, its probably me broke down
Maybe I am just being over cautious seeings how I had to get towed in once on a older boat I use to own.
This one is pretty hard to troubleshoot for me because it is so random.

If it's any consolation, the noise doesn't sound like something that would be catastrophic (grinding, thumping, clunking or scraping). The things you suggested will not hurt the engine, and if it goes away, then all is good.
FYI - Yesterday I experienced a whining high pitched sound coming from my 60 HP 2013 Mercury 4 stroke when starting to move the boat. After some investigation I found out It was an alarm telling me my alternator not charging. Thankfully it was only a fuse.
