Thanks so much Joe. I a just getting into boating and have a 14ft ski-n-troll with the 40HP lohnson mentioned above. You wouldn't happen to know how the bolts are numbered would you. I know, If you the sequense then obviously you know the numbering.
Thanks,
Rick

The cylinder head has 10 bolts. They are numbered exactly as I have them listed. Start tightening with the center left (#1) bolt, then continue on in an ever widening circle.
