I need the torque specs for a 2002 Yamaha 90 2-stroke. And are the rod bolts torque to yield bolts? Can they be reused or need to be changed? I did a complete rebuild and need all the power head torque specs

you can reuse the rod bolts, don't have the spec in front of me, 30 ft# on the rods as i remember, 18 ft# on the head off hand.

I don't think it would hold up to the abuse I put it through. It's on an 18x42 aluminum boat that gets ran in shallow water.
