Not to bash Redline, but I've seen a 24 hour test of gear oil in a differential, and the the Redline did not fare so well. Really poorly on the foaming test. Not sure if they have marine specific gear oil but I imagine the base oil used would not be too different. The test is available online.

Looks like Royal Purple isn't too good either.

We picked up Swepco a while back and have had great results. Some top engine builders and marine mechanics wont use anything else.
