Hi Dave,
For most marine gearboxes the output flange
bearing is a thrust bearing. There to take up the shaft thrust fore and aft.
Try to move that output flange forward or back,
it will seem like it's stuck fast. <insert
discalimer about some nimrod not attempting this while engine is running>
cheers, Russ

the mating surfaces are engaged as they would be

prop's drag actually increasing the pressure on the mating surfaces.
At least that's my theory... until corrected.
Mine rotates in fwd and neutral, not in reverse.
