Where is the drain to change the engine oil

[Ziggy]

You need to pump it out through a small diameter tube inserted into the dipstick

Ziggy is correct. I am thinking you might have a typo in the model #. Is it perhaps a 4JH4-TE? I have 4JH3-TE and can send you manuals by email if you would like. PM me if so.

+1. I also have a 4JH4AE, and change my own oil. I use the 8 qt West Marine oil exchanger to get the job done.

I have a small pump mounted on the engine room wall with a hose to change the oil in the engine and the gear box.

I have been told by a Yanmar agent there is a replacement banjo bolt available for the dipstick connection which has a drilled and tapped hole to allow connecting a sump pump. Otherwise you can take the exisiting banjo bolt to a machine shop to make the same, see Oil changing made easy (well easier)
