Gearbox Oil whats your thoughts?

[looseunit225]

hey guys

just woundering what you guys run for oil in your gear boxes?

i've been running mercury racing stuff in my OMC lightning gear box but i have been told a few people run ATF (auto fluid) in there gearboxes!

i know from when i used to race my track car we used to run ATF in the gearbox and we never had a drama your input would be very apprciated!

cheers

atf!! not when a little water might get in there!!.. i use anglom oil
the mercury stuff is good too.. i find anglom to be better.. u need to be using something that will mix with the water, that atf wont. where as anglom oil and the merc hp stuff will

[looseunit225]

but you shouldnt be getting water in there in the first place!

this is true, it will happen though, and im my case running small gearboxes big props will soon slog out a gearbox i change mine after every race meet.

i change my oil after every practice and every race never found any water in it yet!

I'd steer away from atf for sure.

I use synthetic. On screamandfly.com there is a member in the US who ships their synthetic to screamandfly members with no shipping charges.

I used to change my oil after every weekend of racing, but am no longer seeing metal or any evidence of breakdown of the oil and am going longer.

If the oil you are using is protecting your bearings and gears, staying in the case and not having water problems ... it is good enough.
