There is an error in the Clymer shop manual for Chrysler outboards regarding pinion nut torque for motors 75 hp and larger. Myself and someone else posted a question on this procedure a few months ago. There are two types of lower units for these motors: A one piece unit and a two piece unit that separates into upper and lower halves. The Clymer manual calls for 85 ft-lbs of torque on the pinion gear nut on all units, both one and two piece, 75 HP and larger. The correct setting is 85 ft-lbs of torque for the one piece lower unit only. The procedure for the two piece gearcase is to place the drive shaft horizontally in a vice and swing the housing while tightening the nut. Tighten the nut to the point where you can barely feel the bearings start to bind and stop there. I couldn't figure out why my bearings were so tight until I found the factory service manual and noticed the discrepancy. If you need a factory service manual they can be bought and immediately downloaded onto your computer for $15.00 at www.geocities.com/thechryslercrew
