I just got a 1969 Ski-Doo Alpine. The sled was easy to ID but so far I have been unable to find out the year of the engine. It's a Rotax 399 #1752549. Any idea where I can find the year of the motor? Thanks!

Post it on DOOTalk.com. They will definitely know.

Thanks. I registered there but need to wait on the administrator to give me permissions to post. It's starting to look like my 1969 Alpine model 370E may acctually have the correct motor. I just need to confirm that the 399 is correct for a model 370.
