Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: How much lower unit oil?

Posted by Nightfishin on 12/21/11 - 10:48 AM

Hey guys. Can anyone tell me how much lower unit oil a 48 special should take? I drained the oil and not alot came out and I assumed it was just low. When I went to squirt the new oil in it only took about half a quart before it started overflowing at the top "fill level" port. Does a half quart seem right? I assumed it would take more.

If the oil came out of the top hole, then your lower unit is full.

Thanks. Thats what I thought but I didn't want to blow the foot up for not getting a second opinion.

You're welcome..... it's always best to ask a question first before working on a project than working on a project and asking questions later...

that sounds about right, since my 90 Yamaha takes less than 2/3 of a quart. i've had one guy tell me to fill, plug, then run about 5 minutes on a flusher in gear, then add more, but i don't see the point and it'd be messy.
