I bought my boat in Spring 2016, (2009 Champion 206 with 250 Pro XS) I just changed the lower unit oil the other day, there were some metal shavings on the magnetic plug. Is this an Immediate concern, is it OK to run the boat, should I run it a few times then check it again? My friend helping me change the oil said that it looked like it hasn't been changed in a couple years.. Please let me know your thoughts... Thanks.

If you have a trip planned I would go ahead and change oil and go probably. But if not I would get the lower unit checked out by someone capable of repairing it. If it blows up it can ruin the case and may not be rebuildable. So it kinda depends on how lucky you feel. LOL

That`s quite a lot of metal. Run it one trip and change it again. Sending a PM.

Definitely shouldn't be that much on the magnet! I would have someone remove the bearing carrier and look at the gears.

In your post your friend said it looked like a couple of years on the oil change,,,
I would run it with fresh oil and change it , if it's the same then take it to the shop, if it looks better do it again.
It is normal to have some but not a lot , should be very fine like sand and that is normal on all of them and your NOT sure when the last time it was changed , if ever , I change mine once a year and it's a 1979 and still going strong.


If it was easy, everyone would do it

Agreed. Mine gets changed every 100 hours. I have two hundred hours on my Etec and the lower oil has been changed twice.

If you can feel the shaving when you rub the shaving between your fingers there is gear damage more than likely...OPTI

JFYI do not eas into gear, causes pre-mature shift dog failure. Idle rpm shouldn`t be over 650 in gear. I just put Mystic in my 175 Merc and it shifts much easier. I change my lower unit oil in relation to how I am using it. I will change it 3 to 4 times from March till November.

A couple of trips ago, my propeller struck a hefty portion of concrete ramp while loading my boat at Athens. I had my prop refurbed, but did not think to have the shaft checked out. On the second trip out, my engine started knocking. I shut it down and got a tow back to the dock. Next day, I took it to a very reputable Yamaha shop. The mechanic pulled the drain plug on the lower unit and found a bunch of large shavings. A more thorough inspection showed the lower unit was completely trashed and the prop shaft was definitely bent. Total cost for all repairs, including the $170.00 I had already spent on the prop, came out to $3,500.00. I am convinced that if I had not run the engine with the bent shaft, the lower unit would not have crashed. Live and learn, I suppose.

Definitely more than what you would expect for normal wear. That LU needs service immediately. Cut your losses before you shell the case, lose your prop, etc.
