    Tohatsu 20HP no=spark

    Tohatsu 20HP no=spark

    Of course everything is in the Factory service manual, available from any dealer. An analog ohm meter will be your friend. How do you know it does not have spark?

    I always use the OEM carbs and have had good results.

    Rectifier / Tohatsu Nissan NSF9.8A2

    As km said, VERIFY spark, then VERIFY fuel (which is a more common issue). The rectifier/regulator has nothing to do with starting.

    Put the coupler back where it was... as closely as you can.

    5 hp 4 stroke has water in oil.

    Could be a head gasket. I would change the oil a few times and see if the issue recurs.
