T 8 question

[ffishman]

Its time to change the oil on my T8. This is my first time. The drain is the plug on the left side, half way down the cowling, correct?

[fastrascal]

thats right it is very simple to change but make sure you do not overfill, or it will run like crap..

[ffishman]

Thanks, it states on top of the engine .8 oz. Half a quart. One more thing. I have a 150 merc, and when I change the lower unit lube, I have an attachment that screws into the lower hole, so I can fill from the bottom. Will this same attachment work on the T8 or do I need some other attachment.

8 oz. equals half of a pint, not half of a quart

[rickn]

that might be .8 liters. Mine takes just under a quart to fill.

[ffishman]

OOPS, your right, half a pint. I must have been using the NEW math.

[fastrascal]

no that attachment wont work on the t8 lower unit bolt hole. i just use the oil in the squeeze tubes fot that. hope this helps

I use the same attachment to fill my 150 Yamaha and T-8 lower unit.

yamaha is metric threads and mercury is standard threads. i have a opti main engine and a t-8 kicker. the atachment that works for my old yamaha 40hp works on the t-8. unscrew the attachment and it works on the opti..................tom fellegy

Right, Tom Fellegy.
The poster should simply pick up a Yamaha end for his T-8

Thanks guys, I will look for one. How much lube does the lower unit take?

[Oil]

It .8 quarts. Or about 14 ounces.
