Indmar says 15W-40.
I think I remeber it right that the MC manual says ATF in one place and 15W-40 in another. Dealer says ATF.
ZF manual says ATF, and the 2 ZF reps I have talked to are very suprised by the 15W-40 concept.
Engine/tranny comes shipped from Indmar with 15W-40.
What to use? Has anyone gotten a straight answer on this?
(Note, ZF tranny / v-drive is all in one unit, no separate v-drive).
