Time period of my small Honda

[Mrhtx]

Wondering if someone could tell me approximate time period of my motor
tag is gone but it is a 4 stroke BF 20 -2hp
also if anyone might know of any free pdf style service literature for it? presently trying to access impeller and having problems.
thanks in advance

The serial number or model number might be stamped on the block under the carb at the front of the motor.
You will have to take the cover off.

Any idea on year range ?

1985 is my guess.

Go here for service manual: http://www.boatinfo.no/lib/library.html

For model, year we'll need the serial #s like marc c says.
