Hi Guys,
Just spent all winter rebuilding my '69 Merc 800. Got it into the test tank last weekend. I had some help with the "link and sync" from the mechanic in the photo. Started on the second turn of the key! :D:D

Ran it at idle on AV Low lead at 16 to 1 for about a half hour. Purrrrred. I hope to get it onto the boat in a few weeks. I was wondering, what is the best method to break in my new Baby!:)

Thanks,
Ed

25 to 1 for the first 10-12 gallons of gas vary engine boat speed from 1500 RPMs to 5500 nothing steady up and down up and down.

Then she is ready. JR
