If you are talking about a traditional stuffing box, then 'some'
water while motoring is normal and necessary. However, this should be something like drips/min. - not a trickle or a stream. You may need an adjustment or a repacking - adjustments can be done with the
boat in the water. Some people can repack a stuffing box with the
boat in the water. I can't - if adjustments don't
work and this is not a significant flow, you can wait until your next regular
haul out.
