lower unit gear oil whatcha think ???

[brnschoneck]

ok so this oil is from ooo oct or so changed it today ..no water came out first , but looks real dirty to me is this normal or do u think i need to look at maybe a seal job ??? I did preassure test it and didnt appear to be leaking anywhere but it does look a bit milky/brown to me not sure though thought i may get some suggestions/answers on here
seems to still have its thickness also !!!

For whats it worth, this looks almost identical to 75-90 Volvo Syn geal oil which I just added to my outdrive.

Depends on what your drive is supposed to take. The high perf stuff that I am familiar with is for mercruiser alpha I/O, not sure if it would be appropriate for your drive.

That Pennsoil is just fine for your Merc. You have a standard gearcase on it.


BTW - Mercruiser Alpha drives can use the same stuff. Some swear by synthetic or hi-perf gear oil, but it is not really necessary, IMHO.

I meant for an alpha 1. You need to consult the manual for whatever it is you have

If that oil was in that long I'd run the new for about 25 hours and change again looking hard for metal and water. If you did not change the impeller that certainly needs done.

Re: lower unit gear oil whatcha think ???

YES I DID DO THE IMPELLAR ??? i will run a few times and check again thanks ....

I like to change my lower unit oil in the fall as I winterize. That way if there is water or I have a bad seal, I have all winter to fix, and the water wont freeze and crack the housing. In Michigan watching all the boaters that need all the maintenance done in the spring, is comical. They get mad when the mechanic's tell them 2 weeks, they get really backed up.
Your oil looks just fine, don't forget to replace the paper washer that seals the drain hole!

I like to change mine in Feb before all those that decide March is time to get the boat ready. I use my boat all year and 100 hr services can come at any time....
