The torque sequence for the head bolts on a 1981 OMC 200 typically follows a specific pattern to ensure even tightening. Start by tightening the bolts to 30 ft-lbs in a crisscross pattern. Then, proceed with a final torque of 50 ft-lbs, again in a crisscross sequence. Always refer to the specific service manual for detailed instructions and specifications.
Tighten the head bolts in 2-3 steps to a final 30 NM

in sequence torque bolts to 20nm, then again in sequence turn a futher 120 degrees, and again in sequence 120 degrees.
Torque sequence------------ l 93157 l l 862410 l ------------ Step 1: torque in sequence to 44 Ft/LBS Step 2: in sequence completely loosen all bolts Step : retorque all bolts in sequence to 44 Ft/LBS Step 4: in sequence turn an additional 90 degrees Step 5: in sequence turn an additional 90 degrees Recheck final torque in sequence***CAUTION*** engine uses Torque To yield head bolts (TTY) that permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.
