Changing from regular to hi-perf gear oil

[sjm32157]

I have been using the standard "caramel color" gear lube in my outdrive. I want to switch to the blue-green hi performance lube. Do I need to "rinse" the drive when making the switch? Can I use kerosene or something similar to rinse instead of the $13 a quart hi-perf oil?

No reason to rinse it. Leave the drain out and let it drain over night, put plug in, fill with oil, go boating.

Ayuh,... Agreed,...
They're All very compatible,+ with an overnight drainin', there's nothing there to mix anyways...

Good advice. I'd oly go further to say absolutly do not rinse it.

Thanks for the info. I wish I could "go boating" but I live in Pa and boating season is still 3 - 4 months away.

Plenty of draining time left ......
Agree with not rinsing...just fill her back up.
Remember to use new drain and vent plug gaskets...

My mechanic recommended that I switch to the Merc Hi Performance gear oil from the OMC hi vis I was using and since switching back in 2004 I've had no issues...the oil usually comes out just a bit darker than it went in but the unit shifts very well and is quiet.....
