I just started to install the Vetterman exhaust on my IO-360-M1B engine. The instructions caution not to over tighten the bolts that hold the exhaust tubes together. How tight or loose should these bolts be?
Tight enough it takes two fingers and a thumb to move the aft end of the exhaust. "Snug". Not so loose the joint rattles, but not so tight it renders it useless.
