Changing the lower unit gear oil in Yamaha 250 SHO - DO IT YOURSELF!

Here we continue with our video series on boat motor maintenance. Changing the lower unit oil in the Yamaha 250 SHO is incredibly easy and relatively inexpensive.
All you will need to complete this process is a 4 MM allen head, a flat head screwdriver, and a hand pump. You will need two quarts of yamalube gear oil - check your owners manual for specifics.
As shown, it is a very easy and quick process and when done on a regular basis can extend the life of your motor. I change mine about every 50 hours which might be on the extreme side but I want to make sure this unit last as long as possible.
Similar to the engine oil, I usually do both at the same time to keep the maintenance synced up. I am not sure exactly what yamaha owner's manual says, but I know it is longer than 50 hours. But this maintenance schedule has worked well for me.

Hand Pump: www.amazon.com
That is is really the only items you need. You might have to order a metric allen head because most are standard.

Thanks for showing the process correctly! There is some other guy that did a video on this and he left the outboard tilted up to fill it which is not correct. The Yamaha manual clearly states the outboard should be "verticle", as you have it, when filling.

Thanks. Completed my first lower unit job and saved some money.

How much old fluid would you expect bleed out when changing? > 1qt? Or

Great videos. Did my own the next day. Have you ever serviced the power steering system for your boat? My boat has a Ultraflex system and it is starting to “growl” a little. Looking for info about that system. Thanks

Not yet sorry

Hey, nice video. What kind of hand pump did you use? Couldn't make out the brand.

[@CypressCreekChronicles]

It was from harbor freight

Looking for the washers

[@doubleccatfishing]

The two screws are only to be torqued to 5ft lbs, or you can damage washers
