2013 MERC 60 HP 4 STK GEAR LUBE

[Blue Heron]

Guys

 

Anybody know the correct gear lube for a 2013 60hp merc 4stk - the manual doeasnt say and I cant find much out there - I found 1 spot of merc site that says use premium gear lube (80-90w) for OBs below 75hp

 

Thoughts??

 

Thanks

Just as you stated it but you may want to use the High Performance straight 90 weight synthetic the Premium is 80/90 wt.....it is supposed to give better sealing and allegedly has stuff to keep water out. I know my mechanic buddy laughs at me for being overly conservative but I now do my own winterizing after I had to have new lower unit seals after the marina used the Premium instead of the High Performance in my 135 Optimax. Never have had any problems with the High Performance stuff. Just my 2 cents I know the motors are much different but I always like being conservative

I have been using the premium synthetic in my four stroke Mercury 90 hp

I should have mentioned that mine is a 2 stroke by the way
