Coming up to about 3 years owning my used boat
. It has a Yanmar
4JH-TE with a KBW20 or KBW21 transmission
. I was thinking about changing the marine gear
. Looks like I should be using ATF fluid.
I can't really find any documentation
on how to change the fluid. Is there a drain plug
at the bottom of the transmission
? Is it as simple as opening it, letting the fluid drain and replacing? Or do I need to pump
it out through the dip stick, then replace? Is there a way to clean out the old fluid before adding new fluid?
Thanks for your help!
