outdrive gear oil
I am in process of changing my outdrive gear oil on my XR upper and IMCO lower, Amsoil or Mercury Marine both offer synthetics any thoughts or experiencers?

Nothing but Amsoil in everything I own-motor oil, gear, etc. My mechanic took apart my drives last year and couldn't believe how clean the oil was and how great (no wear) they looked. Bravo ones behind HP500's on a 32 Fountain.

The standard, everyday Merc gear lube is "High Performance", the correct gear lube for XR, #6s, etc is "Extreme Performance". As of 2 years ago Quicksilver Extreme Performance and Mercury Race Gear Lube are the same oils, just different packaging. Also, as of 2 years ago the Extreme and Race are brown in color, not blue like in the past.

George at AADS said he moved away from Severe Gear Amsoil as they did something to the formula that was causing cone clutch failures. No such issue with marine Amsoil.:
