Anyone ever use the Sierra brand High Performance Synthetic Blend Lower unit gear lube? Does it compare to the Mercury High Performance in color (blueish green). Im looking at a 5 gallon pail of it for my TRS boat. It says it is GL-5 rated, recommended for I/O applications and it surpasses the performance of the Mercury High Performance gear lube. 5 gallons of it is 157.00 at West Marine vs $200 for a 5 gallon pail of the Mercury High Performance gear lube.

Yes still sell it and use it for Service Boats asking for it. Mostly been using Mystik for the past 3 years and the price is even better yet..
Sierra also makes a full syn gear oil. The semi syn from Sierra actually works fairly well in Volvo's to and stock mercruiser apps especially Alpha apps..

I have run Sierra lube in my Sportmasters without any issues for years also.
