Knocking noise in gears

Post by Domino »

I have a 2013 262 with Volvo 6.2 380 H. P., put in water for 1st time of year yesterday. Sounds like u-joints are knocking badly. Can they be lubricated (if so,how?). If not is this a serious and expensive problem? Boat goes in foreword and reverse,just making loud knocking noise.

Agree .
Be careful not to run your engine with the outdrive trimmed above 1/4 or close to trailer angles as this also wrecks gimbal bearings and u joints.

Good to catch it now!

Water intrusion is the only thing I've had kill the gimble/U-Joints, the drive up thing is a wives tail. The Engineers wouldn't allow the drive to go high enough to bind the joints, even in trailer mode.

Well my “ Wife” explained that starting your outdrive in up position does two things as the shaft is still spinning in neutral with “ no load “.
Pinion Angle at the ujoint is prone to create a movement that puts side loads on the joint.
Plus the saddle horns built into the housing looses is bracing of the drive and creates more movement.
But you how wives tales can be :lol:
