I agree with Hellosailor.
I also often take out the speed log to clean it.
This is one of the (few) advantages of a very shallow bilge of Benneteau 423. The sounder is less than a feet under the surface, so the preasure is really low and not like a fire hose. It is an easy accesible place - remove one floor panel in front cabin. Easy to do replacement - one plastic out, another in -finished in seconds.
I would not undertake the work with the gland - too complicated and in most boats not an easy to reach place. Not to mention that if it all fails for the sounder case you can easy use a wooden plug. Not so easy with the shaft...
my "HPF" rating for the speed removal -7 the first time, 5 the second and 2 to 3 every other time.
