Serial number

[Thomas Ros]

Hello everybody!
I am new at this forum, but I had my open 19” boat from 1975 since 2008 with motor model 5101.
The homeport is Tullinge just outside Stockholm, Sweden.
The boat has not been in the water for the last six years but this summer we decided to launch the boat again.
After changing oil, gasoline, cleaning the carburetor and change all hoses we tried to start the motor.
After 3 attempts the motor run perfectly, quite impressing!!
But now a question about the age of the motor, the serial no. is probably 205227.
Does anybody know the year of the motor?
Best regards
Thomas Ros

the casting date of the motor should be on the block casting, below the manifold behind the carburetor and flame arrestor. Format will be MMDDYY, just above the number you gave.

look at post#35 of this page, 4th picture

Serial number is stamped under the oil fill and possibly on the flywheel and the date stamp where SURCOUF said...
Under the manifold.
PICS to help...
