To my knowledge the 3LM is most likely a 'marinized' Yanmar industrial/tractor engine and not originally a Yanmar Marine engine.
It should be a sticker or number plate on the gearbox stating make, model, ratio and in most cases even oil to be used.
If you are not able to find that, take a pic and post or up-load on Photobucket or similar and post the link.
