Read articles →An owner walking through a block heater install on a Yanmar YM347, this video covers the full procedure: draining coolant, removing the wire shield bracket, locating the heater port, and torquing the heater to spec (74-85 ft-lbs). It also flags a practical tip, no need to cut the bracket as the instructions suggest. Best for YM347 owners tackling this job themselves.

No. The instructions say to cut the bracket for socket access, but it is not necessary since the whole bracket slides out in about two minutes.
The heater plug is tightened to 74 to 85 foot-pounds.
It is on the right side of the engine block, behind the wire sets, right next to the starter.
A 36 mm socket is used to tighten the heater once the shield bracket is removed for access.
