i think that means that your seals are bad and need to be replaced. you wanna check the impeller and the shaft for any damage becuase thats what probably made your seals go bad. do a search for "water pump" and youll probably find a lot of info. also for a service manual look for Sidewinders (a member on here) post's, he has sooo much info is his signature.. manuals, service manuals, jetting facts, gearing facts lol he has it all.
