drive shaft housing lower seal

1999 Gen 2 alpha 1 outdrive-<br />Split casing and noticed a puddle of gear oil on my water pump housing. The lower seals in the drive shaft housing are leaking. (Towards the end of the season I noticed a little oil coming from the weep holes).<br />Anyway, this looks like a difficult job to replace these seals as you need to pull everything from the housing. Anyone performed this operation yet? Any special tools ?<br />I think I will just bring the housing to my dealer and have them replace the seals. Looks like it may take someone with experience an hour or so.<br />Thanks much!

when you split the upper and lower oil will spill from the upper because the shaft from the lower is what keeps it sealed<br /><br /><br />the seal below the water pump is the only easy one to change after that it starts to require a bunch of tools<br /><br /><br />i just resealed my drive and it was not that hard BUT we have a night school here with all the tools and a teacher to keep you from doing anything to dumb the first time <br /><br /><br />tommays

Well I suspect as I had the gear oil slowly coming thru the weep holes on the outdrive. I can only assume that was indeed the issue as the o ring between the housings was fine. That is the only other place it could come from.<br />You guys looking for more practice at night school?

see that black plastic housing at the bottom of the drive shaft in the above pic? carefully pry it out with 2 screw drivers or you can attempt the useless tool that merc has, buy the complete pump kit and it comes with a new seal housing with the seals already installed and the oring. I paint them with perfect seal (OD only) before I install them.
