I need torque specs for head bolts. Anyone have an answer?

I recently acquired a 1971 Glastron tri hull with a Johnson v100 hydro electric. I am in the process of having work done on the motor. In particular, I am replacing head gaskets and need the bolt torque specifications. Any help is much appreciated.

 

That is pretty model specific. I'd try: Johnson Customer Support Services at 847-689-7090. For fastest service, please have the serial number and model number of your motor available for the technician who answers your call.

 

Thanks for the information.
