Hey gang,

I am almost done with my full bellows job on my 2002 searay 176. I did run into a few problem areas and wanted to ask the experts if my solutions were acceptable.

First, the alum retaining ring for the ujoint bellows did not want to go in so I used my finger with a little 10w30 to lube the bellows and the alum ring. I did not get a bunch on there but just enough to make it a bit slippery and it went right in. It is in there solid and I can lift the housing up and down and doesn't seem like it would slip out. Am I in any danger of that little bit out oil in there making it slip out?

Second problem was when I checked the engine alignment. I did not change the gimbal bearing nor did I mess with the motor mounts and the alignment was a little off. It was a little resistant when I pushed it in and the spline marks were on the top and not the bottom. I then followed the directions here about using a rubber mallet with the alignment tool to hit the top/bottom/left/right sides and then checked again and not the spline marks go all the way around but its still a little hard to push in and out. It doesn't take a lot of force but its not "two finger" like some have described. Should I leave it alone or start cranking on the motor mount?

Last issue is with the exhaust bellows. First thing is I used bellows adhesive on the transom side, will this cause any issue other than being harder to take off next time? On the bell housing side I was able to get it on with my homemade tool but its not seated all the way against the bell housing, these is probably a 1/4in gap. The clamp tightened solidly, will this slip off and if it does will it cause any issue.

This has been my first boat wrenching exercise and overall has not been too hard, as long as the boat doesn't sink when I put in it the water I would say it was an overall success.

Not sure how the oil will do on the bellows ring (It's Stainless steel by the way). Recommended is to use Merc Powertuner since it evaporates after a short time and things stay put.

The exhaust bellows is another example of a perfect place for that Powertuner.

Ok so you freaked me out a bit about using a touch of oil so I went out and was able to pull the stainless ring out without damaging it. I wiped the inside of the bellows and the ring with a paper towel then reinserted the ring. I got to looking at all of this and frankly I don't see how it could come loose. The big quad seal goes up against the stainless ring and then the drive presses that quad seal into the stainless ring so it ain't coming out the way it went in once its assembled. The only possible thing I could see happening is the bellows slipping out of the groove its pressed into but I think that's a long shot...at least I hope. Does that rubber react negatively to 10w30?

The stainless ring needs to be in and FULLY SEATED before you put the rubber ring in and the drive on. If you don't seat it properly, the bellows WILL slip out from under it. The problem with using oil is that it will always stay there, and give the retainer ring a chance of slipping.

Ok so since I removed it (actually twice now) and wiped any residual oil away and reseated with the proper tool do you guys think its ok now? I moved the drive up as far as I could by hand and nothing seemed to move.

If the bellows didn't slip out with the bell-housing in the full UP position or full left and right, you're probably good to go. Is the ring in the same place as where the old one was on the old bellows?

Remember, you're doing the job, not us. We can't see and feel what you can. All we can go on is what you write here.

no way for anybody here to positively tell you that it is seated properly, but...

as long as the bellows was seated properly on the bell housing lip and the ring seated fully, you should be fine

as stated previously merc power tune is the best lube to install the ring, as far as exhaust bellows i always install them dry

Re: Alpha One gen II bellows replacement - Few questions

I haven't turned it full left or right yet but will before I put the drive one. I can't really tell if its in the sales spot as the old one but I can tell you that it's in as far as it will go. I have the tool to intert it and I put quite a bit of force on it to push it in. I used a ruler to measure the distance from the edge of the ring to the edge of the bell opening and it is the same all the way around s I know it's not cockeyed.
