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

Ask them to fax you the picture of the correct torque sequence if it is not marked on the cylinder head
