5000 series.All was running ok to haul out last fall.Removing prop this happened With prop shaft unhooked,I can rotate transmission output shaft 2 to 5 turns then locks up.Rotate it back 1/8 inch or less then rotates fine.Can do this either direction.Fluid levels o.k. no filings ever when changing fluid.Approx.850 hours.
 
sounds like clutch disk grabbing its probably an aggressive tranny on engagement we bring them up to about 1200 or a bit more and pull the shifter back till it slips a bit it smooths the plates up so they shift easier adding a trolling valve lets you bleed off pressure and slip the tranny all day to get a slower trolling speed the plates tolerate this a very long time

I think your talking about a ZF transmission not a Velvet Drive.

It aint broke don't fix it.
 
Why would it lock?I thought these transmission should freewheel,not lock up.
 
Locking up sounds to me like a bad bearing or gear. Have it checked out.
