moving the engagement dogs. I'm pretty sure that the recommended lubricant
is considerably thinner (lower viscosity) than typical SAE90 gear lube.

If no one else chimes in by this evening when I return home, I'll check my
owners' manual and report on the proper lube specs.


Hope you don't mind me jumping in on this thread - but the
non-conductive gear lube comment has caught my attention. I'm hoping to

this week, but had not considered the need for special gear oil in the
lower unit. I've just filled it with fresh outboard lower unit lube from
my local Canadian Tire store. Should I drain and refill it before the
test run with something else? Is this oil only available from the
dealer, or should I look for a DOT or grade specification on the oil I
