Can anyone tell me what the correct headbolt torque is for a new Yamaha 2 stroke 150hp. Is there anything else that should be done after the first 20 hours of operation other than changing gear oil and re-torqueing heads. The dealer wants $200 to do this and a few other checks. Thanks

Call up Yamaha customer service at 866 894-1626. Have the complete model number and serial number and they will give you the correct information. They open at 8:30 EST. They are always very helpful. Ask them to fax you the picture of the correct torque sequence if it is not marked on the cylinder head
