It can be gears or a loose bushing or bearing.
Also, it could be a u-joint

Could it be that the noise does not really disappear but gets lost between other noises when you increase the rpm?
To quickly find out if it originates from an u-joint, turn the outdrive from left to right at idle rpm. If the noise doesn't change substantially, the problem is in the lower gear case.

Unscrew the bottom plug a few turns and see what comes out: water, milk, oil with metal scrapings etc. If it is just clean gear oil and the level seems OK, accept the noise for this boating season.
