Sea water pump leak on 4.3L

[buick6472]

During winterizing yesterday I noticed a small leak on my sea water pump and pinpointed it as a shaft seal leak. I've heard these can be rebuilt. Is rebuilding the way to go? Or should I purchase a new pump? Haven't priced either way yet. I replaced the impeller recently also. Could I have done something during impeller installation to start the leak? 96' 4.3L Volvo penta with SX drive.

They made about 30 different 4.3 models.
Most use the same pump,some don't.
ALL are expensive some where between 3-400$
So a rebuild is the way to go.
Post the serial#s and model#s and anything that helps identify your unit.
Fill out the profile,location?
You might be close to someone who can help?

read the entire post and you will find links to a pdf with a diagram and part numbers for your pump....or you at least
should be able to, unless you have something very strange.
