lower unit lube smells a lot different than 2 stroke oil.
smell it.
If it is clean 2 stroke oil , it is probably running down the drive shaft from the power head.
need to find out where it is coming from up there
is this motor an auto lube or premix?Last edited by 99yam40; 02-11-2018, 10:32 AM.

I tried to paste it but was blocked.
WTF?

Drop the lower, tilt it up like it would if it was still attached. Note where it leaks from. Reseal and replace gear oil. Drive shaft/shift rod seal?2000 Yamaha OX66 250HP SX250TXRY 61AX103847T

Should be two oil seals for the driveshaft and one for the shift shaft. Also two orings for the seal carriers for each shaft.
There is thick blue line at the top of the page, on the left side in the blue line is three short grey lines. Click on the grey line and you will see "buy yamaha parts" Find your engine. The LU parts diagram will show you the seals you will need. If you have the money you may a well do your water pump while you are in there.
Did you drain your LU oil and see if there is any water in there as suggested earlier?
Do you know if the LU has been off before or in the last several years at least?
Keep us posted on how you are doing and what you find.Last edited by panasonic; 02-13-2018, 01:32 AM.
