Bravo One Prop Shaft Oil Seal
 

My seal is leaking. Anyone ever change one?? Any suggestions, special tools needed, lessons learned?? thx. Jon

Yep, Rebuilt my drives myself. Takes several specialtiy tools.
You need the carrier nut wrench, and then a puller to remove the prop shaft carrier. There is also a tool to set the depth of the 2 seals, however if your shaft has gotten grooved, you might ???? be able to set the seals at a different depth so they run on a non worn area. Then to reinstall the carrier (depending if you have the crush ring or shims), gotta set your bearing preload using a good in/pd torque gauge.

You NEED the tools and a manual. Probably cheaper to have it fixed vs doing it yourself. Being a tool maker, I made all my tools and improved on many over the merc design.

I just had one of mine done under warranty.They changed the pinion also from what I have heard that is recommended.Check your bellows also they sometimes go when the pinion gets rust on it and it takes out the seal.

Thx! I am not going to attempt it, especially not having the special tools. I'll leave it to the professionals and have them check the shaft seal contact area and get the preloads set correctly! Appreciate the input.

thx! I 'll have the professionals do it and check the pinion and bellows while they arr in there!

thx
 

took it to a good Merc Mechanic in Central NY and he saw that i did not re-install the plug crush washer seal with the plug
